DTG has assumably bought the licenses to a lot of tracks from Tense Momentum, which in themselves have different mixes such as for powerful atmospherics. I believe these mixes, such as No Room For Error 2 ( https://www.audionetwork.com/browse/m/track/no-room-for-error-2_108313 ), would make great loading music for the routes they're tied to... ...For instance, No Room For Error was bought to promote TSW Great Western Express and has painted the face for its high speed action and being the first route to introduce commuting and passengers. No Room For Error 2 would therefore, being all percussion, make a good loop that prepares you for the game. Other mixes such as the no-percussion mix (No Room For Error 4) would make significant cinematic feelings to the game in scenarios where you bring a service up to speed: perhaps over 70mph during Down The Line? Speak your thoughts about whether DTG / TSW should build atmosphere by using music:
Or how about the sound of passing trains or station noise whilst on the loading screen? Find the music a bit cheesy personally.
