|Keeping Up with the Diesels Scenario (Free DLC)|
|Availability||Formerly available from Steam.|
|Scenarios||One career scenario|
Keeping Up with the Diesels was a free add-on released on Steam for the East Coast Main Line route with one scenario, set around the last days of steam.
- "It is 1967, nearing the end of the steam era. Diesels are being used more and more to haul coal out of Thrislington Quarry but the scheduled diesel locomotive has failed. Drive a Black 5 to transport a consist of coal to Tyne Yard then perform duties around Dunston Staithes. This last-minute change means you are still following the diesel timetable so do your best to keep on time with the deliveries. Keeping Up with the Diesels is a totally free scenario add-on for RailWorks and requires no other DLC content to play."
