I was wondering if people on this forum knew of many that were open to the public, in the London area?
The distinction I make between a 'Garden', Minature/Park railway is that with the latter you can ride on the trains, whereas the former are generally models only. (I appreciate that the distinction may get blurred with some 3/5 inch gauge lines on raised track.)
This comes under models and simulation, because I felt it was the best fit, No objection the the Mods moving it, if felt appropriate.
The North London Model Engineering Society have monthly open days at their track at Colney Heath, between St Albans and Hatfield.Just off the A10 near Hertford is the East Herts Miniature railway, within the Van Hage garden centre at Great Amwell, they are open most weekends throughout the year.
