The final London Midland trains in non-LM livery are being refreshed and repainted by Chrysalis Rail at Bristol’s Barton Hill depot.
The three class 150s, of which two are needed in service on a daily basis, will receive the train operator’s new livery and have corrosion repairs carried out.
Although there is no paint booth at the depot, the work is able to be carried out by using a portable paint room that can be erected in 12 hours and adapted to accommodate different types of vehicles.
Each vehicle takes around a week to complete with the final two car class 150s due to be released from Bristol on November 19.
