This relative of mine is a serious model railway builder. If you don't know
him, I suggest you write: Brian Rowling 42 Pemberton Street NORTH PARRAMATTA
NSW 2151. His layout is a building approx 50 x 20 feet. He has some expertise
in command control and track circuiting. Was a signal electrician at the time
I was an electrical fitter.

Anything at railhead height is a no no! I used to have to work underneath
trains, I was disciplined officially for screwing up handbrakes in case my
train got bumped. I was told that the white flag fastened at the end of the
car set was sufficient protection!! The gap between the sleepers and the 
traction
motors, always seemed too small for awkward Alec....
