. . . . AWS ramps... When did it appear? And does it look different on different regions?


Originally called ATC one of the earliest was in 1905 on the Fairford branch that is part of my Claywell railway and until is closed, the 22mile Fairford Branch was devoid of any distant signals.

However the ATC system was different from the AWS system we use today and the ramps looked very different.  It actually was a ramp, which lifted a shoe on the bottom of the train, whereas AWS relies on magnets rather than physical contact. 

AWS started appearing in the early 50s and is now universal.  ATC would only have been fitted on GWR routes and was gradually superseded by AWS, with the last ones going sometime around the mid-70s.

Must admit I'd not thought of water troughs. Now that would be a neat piece of detailing :hmmm:

I added id plates to my two signals today.  the signs were pre cut but so tiny it was a challenge to stick them on the signal posts and get them square.  I added a phone to one of the posts as well.

I have also re-done the limited clearance signs on my bridges so they line up a bit better.

I added detailing to two of my 37s at one end but had to remove some bits as they were hitting the coupling socket on curves! multiple working cables can stay on though.

If you're modelling the modern GW lines, then ATP circuits are needed, and the loops with then. They look like extension leads laid along the centre of the rack, with the return part attached to the inside of the running rail.

Also the TPWS grids for overspeed and stop grids. In bay platforms you have overspeed grids 55yds before the blocks, and must be under 10mph over them.

On the subject of toilet flushing, at Paddington the platform lines are covered with a membrane to collect the flushings, and every so often a company come along at night to replace them. When we run HSTs into Waterloo during blockades, NR lay the same membranes there on 1 or 2 platforms and the HSTs must go in those.
