I imagined what would happen if I owned a city railway. The first thing people would think is "is this a toy train?" Because the trains are very small and they have a face on the front of them. The face on the front of the train would be lighting shaped like a face to show kindness to the passengers and light up the space in front of the train for safety.
The trains would be so small that there is only one row of seats on one side of the train, there is also doors only on one side of the train, opposite the seats. The reason is because there would be more trains and they would run parallel on separate tracks, as soon as one train leaves a station, another train is directly behind it. The trains would weigh less so they wouldn't put much stress on the tracks and sleeper blocks. The wheel bearings on the train would also have less weight pressing on them. The passengers on the train would have a lot of space and a bike rack next to their seats. Each train would only go to one station from the platform, there would be a train stopping for every station over time and they would skip stations until they get to the one station they are heading for.
When there are very few commuters, perhaps at 22:00, there would be less trains running and they would use less power because the electric motor would have less mass to overcome. But when it is busy, the work load is spread out evenly across the whole line so it would be quicker and more efficient than normal metro systems.
Perhaps this thought only makes sense to me.
