Rivet released an image of a new station render, and people were pointing out that it looks like Partick station on the Argyle Line and North Clyde Line. So, if this is Partick, it has to be one of these routes. It could be either, as both use the Class 318, 320 and 334. The Argyle Line uses the Class 385 as well, but that's besides the point. My bet is on the Argyle Line, as it has less stations and has more variety on its route. Rivet could use the same sounds on the 318 and 320, as they are based on the same model. The 334 and 385 do have a chance, as Rivet is absolutely better at newer motor sounds, the 484 and the 523, for example. What would your bet be on?
