Longest trains we run, due to platform lengths, are 8 carriages, which are made up from
two 4 car sets. We used to run 10 Car Interurbans, but it was decided that they were just
too long. They were made up from a 6 car and a 4 car set.

8 car sets run on all lines every few minutes during the peak hour. Usually every 15
minutes during off peak. The heaviest loading would have to be on the Western line.
