Sorry, only just discovered this thread, some very interesting miniature railway views.
333 is definitely Cleethorpes, loco is Severn Lamb steam outline 2-8-0 7217 of 1972, as rebuilt by the CCLR 1992.
301 is Ferry Meadows, loco 'Henry' by Dove (1950)
338 is also Ferry Meadows, I believe the loco is a Bo-Bo built by A Mills (1986), now rebuilt as 'Norfolk Harvester' at the Wells & Walsingham
339 is again Ferry Meadows, loco 'Alice' by A Mills (1977), present location unknown
309 is the 7 1/4" line at Pleasurewood Hills
313 is an interesting one, the loco is indeed Guest's 'Prince Charles' (later 'Sir Winston Churchill', nowadays 'Prince William') during the period it was owned by William McAlpine, used on a temporary line at events, and lettered RHDR on the tender as a Romney impostor (McAlpine was of course instrumental in saving the RH&DR about this time).
Nice to see 303, that line must have been a nightmare for the operator in the sand. Loco now at Oakwood Theme Park in South Wales.
Just to correct a point here (that I have seen elsewhere online too). The railway at Billing uses SL 15.5.78, a 2-8-0 that originated in Cleethorpes and was rebuilt at Windmill Farm and has nothing to do with the American Adventure line. A couple of rides did go to Billing, but not the railway.
The American Adventure line went lock stock and barrel to Twinlakes Park near Melton Mowbray. The AA locos are actually SL 2-6-0s of a larger overall design than the 2-8-0s and are pretty unique as only four were built to this design, the other two being 60cm gauge ones exported and seemingly vanished. The trackwork from the park had originated at the Liverpool Garden Festival in 1984. I wrote a history of the line at Britannia Park/American Adventure many years ago for the Narrow Gauge Railway Society which now needs an update...
