Ellie is a simple live steam tram engine design for G1 and 32mm with parts and book from Camden. Interestingly google “A-not-so-I” fed me the wrong picture of a standard narrow gauge engine.
EDMES secretary is building one so it will hopefully give him the impetus to drive the club construction stalwarts to build a smaller gauge track now the mammoth task of the 5/7.25 60ft viaduct is operational.
