My list of future loco projects include the following (not in any particular order of priority).
If anyone is interested in these, perhaps some collaboration may be mutually beneficial?
LNER O4 2-8-0 (Robinson GCR design also built for War Dept/R.O.D. and several acquired from W.D. by the GWR and LNWR).
LMS (ex-LNW) Bowen-Cooke Class G2/G2a 0-8-0
LMS (LT&SR design) "Tilbury Tank" 4-4-2T (from 1930s many were reallocated to the Midlands when displaced from the LT&S by Stanier 2-6-4 tanks)
LNER (GNR) D2 Ivatt 4-4-0
LNER (GNR) C12 Ivatt 4-4-2T
LNER (GNR) J6 0-6-0
All these classes lasted into BR days.
The intention would be to power these by battery with radio control and sound.
