One key difference between the Piccadilly and the Bakerloo however is that most stations on the Picc have multi-home signals whereby if a train is departing a platform another train can follow up quite close behind. The Bakerloo only has ordinary running signals between stations (excluding those places with drawups), meaning that if a train has departed a platform it will be a bit longer before the following train enters the platform because it has further to travel and thus will have built up a bit more speed. I seem to remember there being a few multi home signal areas in tunnel section on Bakerloo 🤔

There are a handful of draw ups at a limited number of locations.

I'm not disputing you're right, just my memory may be different from reality haha!

To me, it stands for Train Crew Depot, not sure what it means in this reference but assume the 'D' is for diagram

At the risk of repeating Moderator/Admin advice yet again, would everybody PLEASE remember to explain abbreviations and acronyms in the first instance. It’s not difficult and helps those of us not in the know to better understand what can sometimes appear to be gobbledegook....
