The Underground train I miss the most. The sounds of the doors, the clanking on the rails, the rusty smell, the traction motors. There’s none that have been kept in running condition, so having it on Train Sim World would be the next best thing. I’m sure the C stock has been mentioned before, but I think a DLC with this and the A stock would be an absolutely brilliant addition. Perhaps the whole Circle Line route so you can go round and round? Please Dovetail!
If we ever got a Circle/H&C Line then this is the stock I would like to see, rather than the S. About the only good feature in World Of Subways 3 was that TML captured the essence and sound of these trains (though least said about physics, the better!). The issue remains sadly that DTG seems to have developed anathema against doing any routes that require extensive modelling of sub surface stations, as their talent struggles with the light baking required to make them work in Unreal.
