I have just uploaded another set of repaints to the DPSimulation website, courtesy of Richard Fletcher.
Utilising the Just Trains 'Advanced' Class 20, these repaints feature the class in 'BR Telecommunications' livery and two different packs are available featuring disc and headcode variants.
Please note that along with the requirement of the Just Trains 'Advanced' Class 20, you also must have the Armstrong Powerhouse Class 20 pack installed.
You can find these downloads on the locomotives section of Richard's page by following this link.
