Ages ago I signed up for a community day at Metro trains, who run the suburban rail network within Melbourne. The day arrived and I got to get my gunzel on and learn a lot about how the network is run. We got to look at signals and trains and I got to drive a train on the train simulator!
This photo is of a model Hitachi, which is an older style train that no longer runs in Melbourne. The model itself was of one carriage, and was about 1.5m long.
