Chiltern Railways has invited proposals from established rolling stock owners for the lease and maintenance of between 25 and 70 existing vehicles to operate inter-city and regional services on the Chiltern Main Line between London Marylebone and Birmingham.

The operator is seeking either ‘self-powered’ multiple units or locomotive-hauled coaches, which can operate at 160 km/h in fixed formations of five or six passenger vehicles.

RAIL notes that on December 9 last year, TransPennine Express ended its use of Class 68s and its new CAF Mk. 5 coaches, with the 52 standard carriages and 14 driving trailers built by Spanish manufacturer CAF between 2017 and 2019 facing an uncertain future.

Reports suggest that the lease on the vehicles, including the locomotives, which are hired from Direct Rail Services, will continue until May despite the vehicles not being used. The 13 five-car sets (including Driving Trailers) will not be replaced.

TPE’s fleet of Class 185 diesel units will therefore be worked harder to cover for the shortfall, with short-formed trains of three cars instead of five and six cars on some routes inevitable.

Chiltern's view

Though it declined to comment on whether it has received an offer from Direct Rail Services, Tim Sayer, Engineering and Safety Director at Chiltern Railways, said: "ORR figures show that we have the oldest trains by average age in the country, and as part of our Right Route 2030 Vision, we know that we need to modernise and provide the capacity boost that our customers want and deserve as demand for our services increases."

"As such, we are currently scoping the market for existing rolling stock that can boost our capacity in the short to medium term. As our fleet ages, the communities we serve continue to grow, highlighting the need for a strategic plan to deliver more capacity to the network."

Contract scope

Requests to participate in Chiltern's contract are required by February 2, with driver training planned for 2024, and entry to passenger service for early 2025. The stock would be leased for between three and 12 years.
