For the op, here are some more details. The metropolitan line was the first underground line in the world. It was built using the cut and cover method so it is a subsurface line as opposed to the bakerloo line which is deep level. It is 41.4 miles long and has branches to Watford and Uxbridge. There are 34 stations in total. It is mainly above ground. It is served by the s stock, the newest of the subsurface stock that replaced the older a stock it has the possibility for circle line and Hammersmith and city lines in the track they share with the metropolitan line these use the same trains.
