Busway reopens 30 March - but with temporary timetables

At last! The "temporary" diversion, avoiding the Busway A14 overbridge, is finally going to be lifted, and services will revert to their original routes on Monday 30 March. This will be particularly important for Orchard Park passengers, who have been using the "wrong" stops for 9 months.

However, as previously mentioned, the introduction of Stagecoach's improved Busway timetables has been postponed for a second time. Instead - and for reasons that don't need spelling out here - a reduced service will be introduced on that date. What Stagecoach term an "enhanced Sunday service" will operate Monday-Saturday. It's not quite as bad as that makes it sound - there are certainly additional peak-hour services, and the evening journeys have been retained as well. Service R will be suspended. Sunday services continue unchanged.

Full details, including links to the temporary timetables, are available on the Stagecoach website.

New bus timetables

The timetable changes planned for March 29 will now happen on an as yet unspecified date (although the timetables themselves are currently available for viewing on Traveline). See the revised announcement from Stagecoach:

There’s going to be a huge shake up of Stagecoach’s busway services starting from 29th March. Full details at

Bus diversions on Sunday 8 March

Because of the Cambridge Half Marathon, the needs of the travelling public will once again be very low down the list of priorities, both services B and D severely disrupted.

Busway B
Both Directions
UNTIL 11:30
We will be unable to serve stops on Victoria Avenue, New Square and in the City Centre. During this time, our route towards the City Centre will end at Henry Giles House (Job Centre) on Chesterton Road, and journeys towards St Ives will begin at Mitcham's Corner (outside the Westbrook Centre) .

From 11:30 until 14:00
Journeys will now be able to serve Drummer Street Bus Station, but we will still be unable to serve Victoria Avenue and New Square in both directions. Passengers for these stops are advised to use Drummer Street Bus Station as an alternative.

Busway D
Towards St Ives
UNTIL 11:30
We will be unable to serve stops on New Square, Victoria Avenue, Mitchams Corner and all stops on Milton Road. During this time please use alternative stops located at Cambridge City Centre or at Cambridge Science Park.
From 11:30 until 14:00
We will be unable to serve stops on New Square, Victoria Avenue and Mitchams Corner. During this time please use alternative stops located at Cambridge City Centre or at Union Lane, Milton Road.

Busway damage delaying reopening

Just heard on Monday's Chris Mann show BBC Radio Cambridgeshire @9:34, Richard Wood,  secretary of the Cambridge area bus users' group said that the busway had been damaged recently by, presumably, the A14 upgrade works. No further information - if anyone knows anything please comment here!

New timetables - postponed!

Stagecoach had been planning to introduce new Busway timetables on 1 March (following on from last year's consultation, and the acquisition of additional vehicles). Although the intended timetables are now available to view on Traveline, the rather more important piece of news at this stage is their introduction has been postponed to "an as yet unspecified date". This date will presumably be the one when Highways England and Cambridgeshire County Council finally manage to reopen the stretch of Busway between Histon and Orchard Park. Anyone like to hazard a date for this (I feel I should offer a box of chocolates for the most accurate estimate...)?

Flooding - 18 February

It was still flooded between Fen Drayton and Swavesey when I looked yesterday. But the water is now quite shallow, and there were signs that it might be possible to cycle through. I didn’t try it though.

Now the Great Ouse has flooded again, and it’s not possible to cycle or walk from St Ives Park & Ride to Fen Drayton Lakes.

Flooding continues - 13 February

A picturesque scene. The Cambridgeshire Lake District.
But not so good when you realise that the busway cycle track is still under water between Fen Drayton and Swavesey.

Busway diversion extended YET AGAIN!

Some of those who read this blog may be old enough to remember the time before the Busway was closed between Histon and Orchard Park whilst Highways England worked on the A14 overbridge. Others will simply be too new/young to remember that time.

Well, guess what? The closure (and resulting diversion) is set to continue. According to Highways England: "The new anticipated re-opening date is early March." Keep that date in mind, and we can all return to it in, say, 3 weeks time.

Whilst it's Highways England that is responsible for the never-ending closure - and for preventing Stagecoach introducing new timetables (originally planned for 1 March, but presumably delayed until the diversion is removed) - the County Council hardly covers itself in glory either. At the time of writing, the Council's dedicated Busway website still maintains the fiction that the Busway will reopen in "mid-January". Don't passengers deserve better information than that (the relevant page doesn't seem to have been updated since late-October)? What's happening to money that large-scale developers (e.g. of the Eddington site) are required to pay the County Council for Busway operation/promotion/management?

Full details of the further delay, and Highways England's sort-of-apology ("high-level discussions are taking place on a daily basis"...), can be found in a Cambridge Independent news item.

Flooding 2nd February

Still flooded between Fen Drayton Lakes and Swavesey, though water level has dropped slightly since  I last posted.

Monday, 27 January 2020

Flooding - 26 January

It’s possible now to cycle or walk between St Ives and Fen Drayton Lakes, but there is a lot of debris on the track, so take care.

Between Fen Drayton Lakes and Swavesey, the cycle track is under water, so a detour off the busway is still necessary.

This map extract may help. Please note that the drove which runs past Swavesey Windmill is only designated as a footpath, not a bridleway.

Flooding update - 22 January

The flood gates are closed across the cycle track.

Cycle route between Fen Drayton and Swavesey.

Water still covering the track near St Ives.
These photos were taken today (22 Jan) to illustrate that the cycle track is still flooded. The gates are closed across the track near St Ives Park & Ride and Swavesey, which should indicate to walkers and cyclists not to proceed any further. But still there are nutters who risk their safety by walking and wheeling their bikes along the grassy strip next to the bus track.
It looks as if it will soon be possible to cycle from St Ives to Fen Drayton Lakes, as the water level is rapidly dropping. You might be able to get through on foot if wearing wellies.
East of Fen Drayton Lakes, the flooding seems likely to persist for sone time (se David Parish’s posts). But it is possible to avoid this stretch by detouring via gravel tracks to Swavesey, and rejoin the busway there.

Flooding Update

Last week there was more rain, and the track is now flooded deeper than it was.

Track past the Trout Pond 21st January 2020.
Note the top of the fence behind the ditch is only just visible above the water.

The pipe draining into Covills drain is well under water, but obviously flowing because of the amount of turbulence on the the water above the outlet.
Turbulence above the submerged pipe outlet into Colvills drain. 21st January 2020.
Towards the river Ouse, there is a much larger flow of water - draining the Ferry Lagoon into Colvills drain - back over the breach in the bank.
Water flowing back over the breach in Colvills drain bank. 21st January 2020.
After the level falls a bit more, this flow will stop.

Even if there is no more rain, based on previous experience, it will take at least into March before this section of the track is drained.

Timetable changes from 13 January

[UPDATE 13 Jan, 0835. A friend spotted Stagecoach's announcement of the changes detailed below on the Stagecoach East "Promos and Offers" web page - yes really! That's the only place the information is provided - and it's less complete than my attempt below.

Here are links to: (a) the announcement, and (b) the new timetable.



I was taken by surprise at St Ives Station Road stop this morning to see a new departure sheet posted. I've checked both the Stagecoach and County Council Busway websites and can find no details of changes to services (or even a simple announcement). But new timetables are available from Traveline, and I've attempted below to identify the changes involved.

Note, first, that there are no changes to Sunday services.

As for the rest of the week (including Saturdays)... The most significant changes are to routes A and D. There seems to be a significant increase in journey times on the stretch between Orchard Park and St Ives town centre. How is this reflected in the timetable?

On city-bound trips, most services will depart St Ives 7 minutes (or thereabouts) earlier than at present, and operate 7 (or so) minutes earlier to Orchard Park. Thereafter timings seem unchanged.

On St Ives-bound trips, most services will depart from the city stops as at present, but after Orchard Park will run 7 (or so) minutes later than at present.

There seem to be changes to how the services are being organised in St Ives beyond the town centre. In addition to changes to the times of buses, there may be some switching of routes between the A and the D (and possibly changes to the routes themselves). Check the new timetable carefully!

The first Mon-Fri departure from Ramsey will be at 0605 (i.e. 15 minutes earlier than at present). Morning departures from other villages and towns into St Ives and Cambridge are 5-10 minutes earlier than previously.

There are changes to the routes taken by both services inside the Biomedical Campus. Southbound services will call at the Royal Papworth only as they leave the campus. Northbound services will call at the Royal Papworth only as they first enter the campus.

There are minor changes on route B, affecting - so far as I can see - only the indicative times at intermediate stops. So, for example, outbound services will notionally call at Shire Hall 3 minutes after leaving Drummer St, 2 minutes earlier than at present. (But this seems a pointless change, since it's rare for buses to arrive by the indicative time even on the 5-minute schedule, so why they're any more likely to reach the Shire Hall a full 2 minutes sooner defies logic!)

There seem to be no changes to services south of Trumpington, nor to route B services north of St Ives.

I apologise if I've missed something that's key to an individual reader's particular journey, but there was a lot of data to wade through. And I was aware that those of you heading off for your Monday commute might appreciate some advance warning.

(When I checked at 2300 on Jan 11 the new timetables were not available on the Stagecoach website, only from Traveline.)

Why does the track take so long to drain?

Thanks to Andrew's last post showing how flooded the track still is. I agree this will take a while to drain (typically at least a month when this stretch floods)

But why?

I observe as follows:

With reference to this RSPB leaflet with map:

The stretch that takes ages to drain is where the busway passes between the Trout Pond and Ferry Lagoon.
Typically this section is not the first to flood. Rather the river has to very high before it does flood. But when it floods the water gets trapped.

Covills drain is not marked on the map - it lies just east of the Trout Pond, and runs south to north and drains into the Great Ouse through a flood control gate. Cyclists can identify it by the wedge shaped chunk of concrete across the path where it crosses the east bank of the drain.

When the water gets very high, Covills drain overflows its west bank, pouring water into the Ferry Lagoon. This happened 2 weeks ago.
The observant will note that the west bank of Covills drain is deliberately lower than the east bank (there is only one concrete wedge, not two). This is so the lakes flood in preference to Swavesey.

There is a culvert under the busway just west of the west bank of Colvills drain, balancing the Ferry Lagoon and the Trout Pond. So when water flows into the Ferry Lagoon, it passes through this culvert, and raises the Trout Pond which overflows and floods this stretch of the path.

But how does it drain?  Once the level has got back down to the top of the Colvills drain bank - very slowly.

If you walk along the east bank of Colvills drain about 50-100m north of the busway, you will see across the drain the end of a pipe, which drains the surplus water from Ferry Lagoon through the west bank back into Colvills Drain.

As far as I know (but I am happy to be corrected if anyone knows better) this is the total drainage from the Ferry Lagoon + Trout Pond back towards the river.

This is not very big to drain all that trapped water down by about 1m.  And as the draining continues, the difference in height falls, so the flow through the pipe drops too.

The above photo, taken 31 December, shows water coming out of the pipe - which is completely submersed under water.

This photo, I took a few years ago, looking down on the outlet, with the water lower, shows the flap over the end of the pipe, to prevent water flowing back into the Ferry Lagoon from Covills drain. The flap is pushed open when the water flows in the intended direction, as it is here.

But why is this flow so restricted?

Cycle track flooding update

This photo, taken from the bus this morning, shows the busway cycle track is under water between Swavesey and Fen Drayton. From past experience, the water is likely to remain here for some time.

Saturday 11th January - still flooded.

Thirsday 16th January - now flooded between St Ives Park & Ride and Fen Drayton Lakes, as well as from Fen Drayton to Swavesey.

New closure of cycle track

The busway cycle track between Histon and Orchard Park will close for a month while repairs are carried out. This is the section of busway affected by the A14 widening works, and has been closed to buses for half a year, with buses diverted meanwhile.
