Thank you for bringing this as now I've got a clearer picture of what's going on when watching videos about workers handing in tokens. In these videos is taken for granted that we already know it but it wasn't my case as I am a simple curious veterinarian. Thanks a lot
For some reason, I could never get my head around how TST would work in practice, though with the explanation @ 6:10 where the ticket trains would advise when they'd have arrived complete clarifies it. Funny how things are obvious once they're explained, can't believe I was asking [myself] "but with the ticket, how do you know the single line is clear?"
The last train through brings the staff with it, that signifies nothing else is behind as you can’t issue any more tickets without also showing the driver the staff at the same time. In the case of the cromford and high peak railway, the train staff physically opened the ticket box, you couldn’t get the staff out with the box opened, so had to close and lock it to get it out and hence you couldn’t get more tickets. In the end you still have to have some human interaction, there’s nothing stopping someone offering multiple tickets prior to a rain completing it’s journey to the other end or showing the wrong staff and the driver not looking properly at that , so you still have to enforce rules. It’s the reason it’s important to look at the staff or token and check it’s the right one before proceeding rather than assuming it is, hence following Abermule, one person dispatching tokens and signalling trains, drivers checking the tokens correct for the section prior to departure and interlocking starting signals against the token ,tablet or staff.
