Today I will be suggesting a route for TSW 2. As the title says, it's about the Circle and H&C (Hammersmith & City) lines. Hammersmith & City line The H&C line runs between Hammersmith in West London and Barking in East London. It it's 15.8 miles long. Most of its track is shared with the other Sub Surface lines and all stations are shared aswell. As of December 2012 there are six trains per hour calling at all stations and requiring 15 trains for the peak hour service Circle Line The Circle line runs from Edgware Road looping around Central London back to Edgware Road to then go to Hammersmith. The line is 17 miles long. As of 2012 there are six tph. Calling at all stations requiring 18 trains in service. The lines depot is at Hammersmith. The rolling stock for both lines are the S7 Stock trains. The S7 stock trains entered service on the 2 lines in 2013. The route could be during the transition phase between C69 and S7 Stock trains or could be after the transition phase but before the 4LM process began.
