TFL Metropolitan Line A-stock train.
This A-stock train was built in the early '60's.
There are two sets coupled together for this service, which is the norm as each set has four coaches.
These were built by Cravens in Sheffield but soon will be gradually phased out for the modern S-stock which are now coming into service.
