The page explains the sequence of levers required to signal trains on the AMR, as shown in the video below.

Start by looking the extreme left in the picture, a red lamp will illuminate to indicate "train ready to start."
The signaller pulls levers 2 & 3 (2 is the platform starter signal, and 3 is the next signal out of the loop onto the single line section). The signaller then records the time that lever 3 was pulled on the train register and in the background the station master's whistle can be heard.
Then the signaller pulls lever 6 (to allow the train into the 'neck' beyond the loop at Wesley's Halt, though this is for practice, the signal is not there yet)!
In the absence of a track diagram, the signaller makes several observations through the window, and once it is certain that the train has departed, lever 2 is returned to Normal.
After a few seconds, the train has passed signal 3, so lever 3 is returned to normal; and then lever 1 is pulled to let the previous incoming train into the loop (up to signal 3) as a shunt move.
At this stage, the signaller can see the train and the driver, and these details are recorded into the register.
The train's whistle is heard, and the signaller counts the passengers (a duty that will be passed to other staff in due course) and enters that figure into the register.
Lever 1 is returned to Normal, having observed that the shunting train is now in the loop at Depot Approach, and lever 4 is pulled for the Shunt signal to let the train into the departures platform track, to form the next departing train.
Then, lever 4 is returned to Normal.
Lever 7 is pulled when the train has reached Wesley's Halt (this clears signal 7 to allow the waiting train to start its return trip from Wesley's Halt to Depot Approach).
Lever 6 is returned to Normal as the first train enters the 'Neck.'
Once the returning train has passed the signal, lever 7 is returned to Normal, and after a pause, lever 10 is pulled to allow the first train into the waiting area (for its turn past number 7 signal). Like number 6, number 10 signal has not been provided yet, but it is good practice to work as if it has!
Then, the signaller adjusts the train describer (which will eventually tell the station master about the approaching train, but is also used for practice, presently).
Finally, lever 10 is returned to Normal.
The returning train will pass an automatic signal before coming to a rest at the Arrivals platform at Depot Approach.
