Having already a an old Bachmann Big Hauler Royal Blue Line set comprising Locomotive, Tender, Mixed Coach and Observation Coach plus rails and DC Controller etc, I recently set about starting to realise my boyhood passion again of building a model train layout. Indoor Space is not a problem as we have a large amount of Garaging and Shedding on the property. Looking at the information available I decided that the scale of the Existing Set would be 1:20.3 (Largest G Scale) as against 1;22.5 which I assumed would be a smaller scale and so I have purchased a Big Hauler Baldwin Industrial 2-6-0 Mogul P/No 81699 (I believe it is in the correct box) which indicates it to be 1:20.3 Scale. However it is obviously a smaller scale than the Big Hauler "Royal Blue Line" Train I already had. Can someone please clarify this for me as I am remote from any local information and I have to generally order via email/ebay or similar. Thank you
