Paul,
Nice building, you've discovered your true vocation..
I like the Naff Gas Heaters you've modelled. They were so BR.
In the 80's I had a turn one night with a ballast from Ashford to Tonbridge, got relief, 4 hours doing nothing, then relieve and work back to Ashford. Trying to do what any good railwayman would do; sleep, I retired to a quiet room in the west yard. Would the heater work, would it f**k..... Luckily a layer of weekly notices provided an insulating layer on the table that became a bed. I managed a couple of hours kip on a cold december night.
Non railwaymen will have no idea what I'm on about.
If there was a test to see who was a true railwayman, I'd show them four dining chairs and ask what they'd make. A true railwayman would line them up and be asleep before you could say 'Bob Reid'.......
