Royston corridor changes from 30th June (services 17, 26, 31)

There are significant changes coming from Monday 30th June on the Royston corridor and surrounding services.

First to the service numbers themselves:

  • Current service 17 (Guilden Morden-Bassingbourn-Royston) is extended north from Royston.
  • Current service 31 (Fowlmere-Cambridge, plus one daily trip to/from Barley) is being replaced and will in future form part of service 17.

As for the services to be operated:

  • All Cambridge journeys on routes 26 and 17 operate to/from Drummer Street Bus Station. Changing buses at Addenbrooke’s or Trumpington Park & Ride will no longer be required.
  • There will be more services along the main Royston-Cambridge corridor, with earlier northbound and later southbound services than at present – the first weekday bus leaving Royston at 0537 and the last from Cambridge at 1915. [Corrected 27/6/25: the 1915 operates only to Melbourn. In fact, the last bus to Royston is earlier than under the current timetable, 1800 Mon-Fri and 1730 Sat.]
  • Villages between Guilden Morden and Royston will have a number of services operating to/from Cambridge (precise numbers differ, depending on direction and day of the week).
  • Royston and Melbourn will have more services to/from Cambridge, whereas Little Shelford and Thriplow will have fewer services coming through their villages (with Thriplow particularly affected – down to just one per day).
  • All services will in future be operated by A2B Travel Group.

These aren’t the easiest changes to explain in written form, and no amount of text can cover all of the changes involved. If you have any interest in the places currently served by routes 17, 26 and/or 31, then please consult the new timetable.

Thanks to Intalink (Hertfordshire County Council) and Foxton Parish Council for making information available in advance on these changes.

Autonomous minibus trial open for public use

The first of the autonomous bus trials is now open for public use, until March 2026. This Greater Cambridge Partnership Connector project will eventually see autonmous buses on trial in three locations – the first to become available for public use operates to and from Madingley Road Park & Ride, taking in Eddington and West Cambridge. The pilot service is free and the project will be using 15-seater minibuses.

There are four peak-hour round trips each morning and afternoon, Monday to Friday. Total journey time around the loop is 18 minutes.

There will always be a driver on board (provided by Whippet).

Stagecoach 905 – new timetable from Sunday 1st June

Stagecoach are making further changes to their 905 service (Cambridge-St Neots-Bedford). In addition to improving reliability, the changes are also intended to “enhance evening and Sunday connections with Service X5”.

The revised timetable, at time of writing, is temporarily missing from the Stagecoach website and from alternatives such as Traveline and Bustimes.org. Check back nearer the time. is available here.

New services from Tuesday 27th May

A number of new services are being introduced by the Combined Authority (CPCA) with effect from Tuesday 27th May. Contracts have been let to a number of operators.

The immediate Cambridge area will be served by five of the seven new routes.

The CPCA is using its “Tiger” branding for these routes, but passengers will probably be relieved to know that the service numbers will abbreviate this to “T”.

All services operate Monday-Saturday, excluding Bank Holidays.

T1. Operated by Whippet. This is described as a “Cambridge to Huntingdon Express”, although it’s no faster than Whippet’s existing X3. The route follows that of the Stagecoach Busway B (excluding the diversion into Cambridge North tation) as far as Swavesey, then cuts across to Fenstanton and direct to Huntingdon Rail Station. Journeys towards Cambridge also serve Huntingdon Bus Station.

T2. Operated by Stagecoach. This service essentially forms a semicircular route around northern Cambridge, from Newmarket Park & Ride to Madingley Road Park & Ride, via Milton Park & Ride, Impington, Histon and Huntingdon roads Cambridge, and Eddington.

T3. Operated by Stagecoach. The end points of this route are the Ida Darwin Hospital and Grantchester. Amongst the places served along the way are Addenbrooke’s Hospital, Babraham Road Park & Ride, Great Shelford and Trumpington Park & Ride.

T4. Operated by Stagecoach. This one adds to the number of places with direct buses to Addenbrooke’s Hospital. From the Biomedical Campus it serves Fulbourn, the Wilbrahams and Bottisham, continuing to Newmarket mostly along the route already served by Stephenson’s service 11.

T5. Operated by A2B. This service finally reinstates Soham’s direct link with Cambridge (or vice versa, perhaps?). Appropriately it follows the route of the former Cambus service 122 – in more recent times this is the route of Stephenson’s service 11 between Cambridge and Burwell, then continuing to Fordham and Soham.

(For the sake of completeness, the other two new Tiger services being launched on 27th May are the T7 – Chatteris to Wisbech – and the T12 – Longstanton P&R to Sutton.)

More information about these Tiger services (but not timetables – or even links to them) is available from the CPCA website.

Timetables are available from the respective operator’s websites:

In addition, all of the timetable data (including specific stops served) can easily be accessed at other sites, such as bustimes.org.

Stagecoach Busway changes from Sunday 20th April

Stagecoach are introducing changes to Busway services from Sunday 20th April.

The principal change concerns Sunday services during the main part of the day on the “core” section of Busway between St Ives Park & Ride and Cambridge city centre.

Whilst journeys to and from Hinchingbrooke Hospital and Trumpington Park and Ride remain unchanged, the service will now be rounded out with two “A” trips in each direction every hour between St Ives Park and Ride and Cambridge city centre in place of the current single trip on route “B”. The structure of the resulting timetable means that these four buses an hour will be evenly spaced on this “core” section. It’s goodbye to the half-hour gap between buses during the main daytime period.

Additional changes Iapplying all week) involve rerouting of northbound “A” buses to avoid the frequently-congested Gonville Place. So Parkside will no longer be served. There’s also a route change at the northern end of the route in St Ives.

And there will be only two journeys per hour, Monday-Friday, between St Ives Park & Ride and Marley Road, in place of the current three.

There are minor changes to peak-hour weekday timings on route “B”.

Finally, on service 5, the 1730 from Cambridge will no longer operate along the Busway and will terminate at Longstanton Park & Ride.

Further information can be found on the Stagecoach website, which also provides links to the new timetables for all three services.

Revisions to all Whippet routes from 3rd March

Whippet are revising the timetables on all their routes from Monday 3rd March.

In all cases there are minor changes to (try to) improve punctuality. But there are also some more significant changes, as noted below.

18A, 66, X3. Additional buses will operate on Saturdays, thanks to funding from the Combined Authority.

X3. Peak time services starting or ending at Papworth Everard will also serve Hilton and Fenstanton.

More details, and links to the new timetables, are available from the Whippet website.

Minor changes to Stagecoach services 1, 3, 4, 905 and PR1 from 23rd February 2025

Stagecoach are making minor changes to services 1 (Arbury/Fulbourn), 3 (Fison Road/Cherry Hinton), 4 (Cambridge/Cambourne), 905 (Cambridge/St Neots/Bedford) and PR1 (Madingley Road Park & Ride) from Sunday 23rd February. They form part of a larger series of such changes being introduced across Stagecoach East from that date.

The usual booklet is available on the Stagecoach website giving more information (not that there’s much to say on this occasion). And the new timetables can be downloaded as well.

Changes to Whippet rural routes from 2nd December

Whippet are making changes – some major, some minor – to their rural routes from Monday 2nd December.

The main change of relevance to the immediate Cambridge area is to the combined X2/X3 operation. On weekdays an additional hourly service will be added to the timetable between Huntingdon and Cambridge City Centre (not continuing towards the Railway Station and Biomedical Campus), thereby providing a half-hourly frequency throughout most of the day. And there’s an additional X2 departure from Emmanuel Street at 1845, heading to Huntingdon via Addenbrooke’s. There are consequential changes to most departure times, so it will be important to check the new timetable for specific information you might require.

On service 18 there are a couple of minor punctuality-related changes. And, further from Cambridge, an improved frequency, plus additional more minor alterations, on the 66 (St Neots/Huntingdon).

Further information, and links to all of the new timetables, is available on the Whippet website.

Busway B changes from Sunday 3rd November

Busway users need to brace themselves for yet more changes – this will be the fifth Busway timetable to operate in 2024 alone – coming into operation next Sunday, November 3rd, just nine weeks after the previous set. The latest revisions apply only to the Monday to Friday B service, so users of the A need read no further.

There will be a significant reduction in the number of journeys operating between Cambridge City Centre and the Biomedical Campus and/or Long Road 6th Form College. The number of southbound trips along this section of the route is being reduced from thirteen to just five. Northbound journeys are reduced from the current thirteen to four. It’s worth remembering that this southern stretch is served only during peak hours.

But there is better news for passengers between St Ives and Cambridge City Centre. There will be an additional five journeys overall in each direction between the Park & Ride and Drummer Street.

There are also changes to departure times of many services along the whole of route B.

Stagecoach’s announcement notes the significant congestion impacting journey times between the city and the Biomedical Campus. With little immediate (or medium-term) prospect of anything changing in this regard, prospects for the future in this regard look bleak.

A copy of the new timetable is available from the Stagecoach website.

September Bus Changes

There is much to welcome in the September changes to bus services in and around Cambridge announced by Stagecoach and WhippetStagecoach changes from Sunday 1st September, New Whippet service 18a from 2nd September – with increasing funding from Cambridgeshire and Peterborough Combined Authority.

Some services are being ‘rationalised’ (Stagecoach’s citi1 in Fulbourn) others have longer journey times (citi7) or reduced frequency (citi6) whilst others have, currently, no prospect of returning to pre-Covid frequency levels (citi2 every 20 mins, 10 mins pre-Covid).

Cambridge Area Bus Users recognise that commercial bus companies cannot run services at a loss. Adding extra buses to maintain frequencies adds costs, without any certainty of increased farebox revenue. Unless our plethora of overlapping local governance bodies (see graphic, below) take radical action to tackle traffic congestion bus services will be in a spiral of decline: reduced speeds ➞ increased costs ➞ lower ridership ➞ reduced income ➞ service reductions ➞ lower ridership ➞ reduced income ➞ further service reductions.

In February 2024 sister organisation Cambridgeshire Sustainable Travel Alliance issued a press release – We will all lose out if the Greater Cambridge Partnership abandons large-scale projects to reduce congestion.

The current high motor traffic levels are hinted at as the reason for abandoning the road reclassification project. The Eastern Access project, Hills Road and Madingley Road schemes are also being watered down due to the need to accommodate large numbers of cars. It is highly inequitable that projects to encourage people to use sustainable transport and reduce car usage cannot go ahead or are compromised because there are currently too many people driving. Many people who drive would like to travel by sustainable means, but cannot. When GCP officers assessed the threats and opportunities of not proceeding with the Sustainable Travel Zone road charge last September, they did not mention that abandoning road charging would leave them unable to deliver other GCP projects. In hindsight, this is a significant omission.

CSTA press release as above

Silviya Barrett from national transport charity Campaign for Better Transport (a member organisation of the Cambridgeshire Sustaianble Travel Alliance) said: 

“The only way to tackle congestion is to reduce the number of cars on the roads. Traffic reduction measures, coupled with public transport improvements have been proven to cut congestion, reduce air pollution and make places more pleasant to work and live.”

Cambridge Area Bus Users has received multiple complaints about unreliable bus services; one member reported walking from the city centre to the Catholic Church faster than five buses crawling along in road congestion. The group cannot envisage significant improvements in bus reliability until congestion is tackled by reallocating road space away from private cars to buses and active travel.

We contacted David Boden, Business Development Director of Stagecoach East, Chair of the recently-formed Cambridgeshire and Peterborough Bus Alliance, who was kind enough to provide the following statement.

As people who run local buses, we tend to talk about two connected but different concepts: ‘reliability’ and ‘punctuality’. We are very willing to be held accountable for the aspects of reliability we can control – that is to say, providing a bus and a driver when we say we will. But, once the bus leaves the station or depot, its punctuality is overwhelmingly dictated by issues like congestion, parking enforcement and roadworks, none of which are in our power to change.

All this slows the bus down, increases journey times and the cost of service provision, and makes it really difficult to rebalance using the bus over car. There is no secret formula to all this, put simply, if you want a world-class bus network, you need a world-class road network and bus infrastructure.

Our local authorities work very hard to try to mitigate the negative effects of roadworks where they can, but there are sadly limits to their powers.  Now is the time for everyone, including the utility companies, Highways and other key stakeholders, to engage with bus operators directly in a meaningful and productive way.

Buses are a key lifeline for our region, and with a genuine desire from everyone to go that extra mile in minimising disruption to bus services, we can offer the residents of Cambridgeshire the excellent service that we all want them to have.

It is a burning issue. Bus services are not going to get any better – and will continue to get worse – until we have those conversations, and elected officials then are willing to make bold and difficult decisions. [Our emphasis]

I will say that, in recent times, we have seen some elements of progress. We recently praised the communication from UK Power Networks for their Mill Road works, for example. They gave us proper notice and this led to high-level discussions between the two companies, with potential ways to keep disruption to a minimum, floated.

We hope that this will set a template for all such interactions in the future, so it becomes ‘business as usual’ that utility companies talk with the major bus operators so we can all work together as best we can.

Traffic Inducing Traffic

We recognise that funding for comprehensive, fast, frequent bus services cannot rely on farebox revenue alone. Support from the public purse is also essential. That public purse is not inexhaustible; plans for radical improvements to bus services envisaged by Cambridgeshire and Peterborough Combined Authority (our Transport Authority) could founder unless Cambridgeshire County Council (our Highway Authority) and the Greater Cambridge Partnership (holder of the ‘City Deal’ purse strings) “are willing to make bold and difficult decisions“.
