North American commuter trains and express service

[ionelv]

Normally, my commuter train ride (53 km) takes 60 minutes (all stops; avg speed 53kmh) or 50 minutes (semi-express; avg speed 63.5km). Today, due to earlier operational issues and now overlapping with later train, I got a rare treat: full express service which took only 33 minutes (avg speed: 96kmh).
