Easter Disruption For Europe’s Busiest Train Line

The title of this post, is the same as that of this article on the BBC.

This is the sub-heading.

Thousands of Easter train journeys will be disrupted by a six-day shutdown on the West Coast Main Line (WCML).

These two paragraphs add more details.

Engineering work means no intercity services will run between London Euston and Milton Keynes from Good Friday to Wednesday, 8 April, Network Rail said.

The Easter work is part of a £400m project to boost reliability, which WCML said was Europe’s busiest railway line used for passenger and freight trains.

This graphic from London Northwestern Railway, shows the Rail Replacement Bus routes around the blockade.

Note.

1. There are no trains South of Milton Keynes Central
2. There is a Rail Replacement Bus between Milton Keynes Central and Bedford.
3. There is a Rail Replacement Bus between Milton Keynes Central and Watford Junction

This OpenRailwayMap , shows the Marston Vale Line between Milton Keynes Central and Bedford.

Note.

1. The two Bedford stations ; Bedford and Bedford St. Johns are in the North East corner of the map.
2. Milton Keynes Central station is on the Western edge of the map.
3. The Marston Vale Line, which is shown in yellow, links Milton Keynes Central and the two Bedford stations.
4. The track shown in red, going through Milton Keynes Central is the West Coast Main Line.
5. The track shown in orange, going North South through Bedford is the Midland Main Line.
6. The Midland Main Line appears to be running normally between Bedford and St. Pancras. This is according to Real Time Trains.
7. The Marston Vale Line should be running new Class 196 trains, but it is not due to a door opening dispute with the trains.
8. The Marston Vale Line appears to be running normally between Milton Keynes Central and Bedford. This is according to Real Time Trains.

This OpenRailwayMap shows Bletchley station and the flyover on the East side of the station.

Note.

1. The West Coast Main Line is on the West side of the map.
2. Bletchley station is indicated by the blue arrow at the bottom of the map.
3. To the East of the station is Bletchley flyover, which is labelled “Summit of Bletchley Flyover.
4. The flyover splits with one branch going North to Milton Keynes and the other East to Bedford.

It does appear, that no train can go between Milton Keynes Central and Bedford stations, without a reverse at Bletchley station.

But you can go between Milton Keynes Central and Oxford stations, without a reverse at Bletchley station, as you stop on the flyover.

To check, I read the tracks right, I asked Google AI, “Can Trains Go Between Bedford And Milton Keynes Central Without A Reverse At Bletchley and received this answer.

Currently, no. Trains running between Bedford and Milton Keynes Central cannot bypass a reversal (reversing direction) at Bletchley because the Marston Vale line terminates at Bletchley station. Trains must enter Bletchley and then change direction to join the West Coast Main Line to reach Milton Keynes Central.

Key Details:

Current Routing: The Marston Vale line connects Bedford and Bletchley. Services from Bletchley to Milton Keynes Central operate as a separate connection.

The Reversal: Passengers currently must change trains or experience a driver change/reversal at Bletchley to continue.

Future Changes: The East West Rail project aims to improve these connections, but as of early 2026, the direct link remains through Bletchley.

Conclusion

Does this explain, why there is a Rail Replacement Bus rather than a shuttle train between  Bedford And Milton Keynes Central stations?
