Typical circuits, are they available?

If you really want to get on you'll grab every opportunity that comes your way. Just studying the circuits alone is not always enough as you have to understand the equipment and how it works in order to follow the electrical circuits, This is particularly true of the point equipment and trainstops.

Here are some things that you ought to do;

At your next personal development assessment tell your manager that you want to be trained as a signal lineman. You may not yet have enough time in the job to be considered but if you don't ask you are not likely to get.

Also suggest that you would like to be shown example circuits and have them explained by a competent person so that you may increase your knowledge of basic signalling in order to be able to pass the assessment to get on the course.

Ask the TOs you are working with to spend some time explaining principles and circuitry to you, believe it or not part of a TO's job description is to train the staff that assist him/her (yes there are a few female TOs) and there is always time available though not every shift.
Also ask the TOs to give you the chance to test a site from the lever frame, it is the deep end but you'll learn some things very quickly about controlled signalling. You'll also learn to communicate with control room staff in 'signal speak' when things aren't doing what you expect.
It is in a TO's interest to train you if you are willing and receptive, the worst thing in the world as a TO is having a bunch of useless assistants when something needs to be done properly in a hurry!

I think by now you know that there is help here so read the notes that you have acquired and any copies of drawings that you have got and continue to ask questions.

When I was a depot TO I happily trained those that wanted to know as well as those that I needed to know in order to assist me. Of course I worked mostly night shifts so I usually had a spare hour or so waiting for traffic hours to end and subject to dealing with failures such as trains dropping onto the deck running into Ealing Common depot or running through the Switchlocks leaving the depot at Boston Manor etc.

The best thing about training others was what I learnt myself, I think things are different course wise these days with the modular approach but when I trained as a signal lineman it was a continuous slog and geared very much to PWay Ops and signal failures with a great deal left out. Thus it is also up to a TO to train him/herself on the job while working.
