i'm a regular rider on the brighton line, i don't really have a problem with the R46's running on the , it's pretty nostalgic and plus, i honestly prefer the dim lighting, and the fact that they just sound quite a bit quieter than the R160's, because, lets be honest, the propulsion on the R160 is blatantly annoying
(it's easier to take a quick nap on the ride)
however it feels odd but whatever
