Chiltern Railways has expanded on its plans for Class 68s over the next few months.
The operator is
replacing its ageing Mk 3s with Mk 5A stock on the Marylebone-Birmingham Moor Street/Stourbridge Junction route during 2026.
The 14 Beacon Rail locomotives that had been modified for use with the CAF coaches (68019-032) are currently being transferred. So far, 68020/022/032 have been re-vinyled (by Aura Graphics at Eastleigh) in the new
Chiltern two-tone blue livery.
Of the rest of the fleet, 68019/023/026/028-030 have also been actively involved in crew training, 68027/031 are being worked on at the UK Rail Leasing site at Loughborough to allow them to return to use, while 68021/024/025 are still at Direct Rail Services depots - Carlisle Kingmoor, Motherwell and Crewe Coal Yard respectively.
DRS will be relinquishing its lease on 68018, and it will return to Beacon Rail and be directly leased by CR and reliveried. However, it will only be deployed as a thunderbird locomotive as it will not be modified to work with the rolling stock.
The CR ‘68s’, which will also all run on HVO (hydro-treated vegetable oil), are also undergoing some modifications.
As well as featuring stop-start technology which shuts down the engine after a prolonged period of idling, they also have noise insulation and baffles for when they are idling.
To overcome the noise issues that Scarborough residents experienced when ‘68s’ were in use with TransPennine Express, a new shore supply is being installed at Stourbridge Junction, in readiness for the December 2026 timetable when three sets will stable there overnight. This will allow the ‘68s’ to be shut down immediately on arrival.
CR may also take on a fourth siding here, to enable an additional set to stable. Up to four sets will stable at Banbury, and another four at Wembley.
Ten sets a day will be in use, with one spare and two undergoing maintenance. Maintenance on the fleet is currently managed by Beacon and contracted out to Arriva Traincare until December 2026.
Four sets are needed for March 2026 when Mk 3s go off lease, but CR could have up to six ready by then.
It is likely Mk 5As could be introduced in late January or early February, providing sufficient crews are trained on their operation.
