Network Rail test trains have been asked for by many people. Here is my take on which ones should be added. Class 37: We already have the class 37 in TSW3, so it should be easy enough to give it another livery. Network rail class 37 test trains are frequently operated using colas livery class 37s and DRS class 37s. These are used on PLPR test trains and UTU test trains. DBSO: The Network Rail DBSO is in yellow livery and is used on UTU test trains will class 37s. Class 73: The GBRF class 73 is used on PLPR test trains around London and the south east. Class 950 (150): The network rail class 950 is a modified class 150 used on lines with diesel traction. Since we already have the 150 this should be quite easy to make. Class 43 HST (NMT) The new measurement train is equipped with all of Network Rails fancy gadgets. The train runs on uk main lines at speeds of up to 125 mph. Class 313: This train is also already in the game so it would likely be a simple case of stripping out the interior and painting the outside. Im not going to talk about the stock that is used for the test trains because it is just converted old carriages. Routes: SEHS - Class 37, class 73, dbso BML - Class 313, class 73, class 37, dbso ECW - Class 313, class 73, class 37, dbso GWE - NMT, class 37, dbso WCL - Class 950 MML - All of them BBC - Class 950 Cathcart Circle - Class 150 Scotrail Express - NMT, class 37, dbso Since most of the trains listed are already in TSW this DLC should be priced between £10 - £15 Thanks for reading!
The other one was for the track maintenance equipment, I believe, whereas this is stuff like the retrofitted class 43 measurement train with its fancy lasers.
