As a child I used to have one of those Triang ( ? ) metal signal boxes with the flat roof. Never really thought about what it was based on but in this months British Railway Modelling is a six page article on the 'Odeon' or 'Glasshouse' signal boxes of the 1930's Southern Region. Wait a minute that looks a bit like .......... Apart from rust blemishes they were a good example of design economy.
They have one of the Triang ones on the layout @ Butterley but has been 'upgraded' with glazed windows and internal lighting.
The 'OO' layout, which as recently been rebuilt, is run by Alfreton Model Railway Society and the layout & staff are very child friendly. You can also get Hornby kit at 20% RRP and their own loco / truck lighting kits for about =A34 or =A35.
Was the Triang steel footbridge also of Southern origin ? All the ones I can recall in my childhood had open 'mesh' type sides.
