One of the downsides of the increasing availability of reasonably priced rtr models is that a higher proportion of people are prepared to wait for a commissioner or manufacturer to introduce a rtr model than attempt to assemble a kit or scratch build where a kit is not available.
The introduction of the MM rtr diesels probably contributed to Ian McNally's decision to cease producing loco kits and the eventual demise of the MIR range of wagon kits. There have been very few articles on this thread on building 121 locomotive since MM announcement several years ago that they intended to introduce a model of that loco. There appears to be a similar pattern in the UK both with the decrease in the number of model railway shops and decline in kit/component manufacturer.
I had fairly clear objectives in the early 80s that I was going to scratch build ex-MGWR locos and stock for a 21mm gauge layout, instead I ended up building less relevant models as kits of GSWR & GNR locos and stock were released by TMD and SSM and later bitten by the American railroad bug and an interest in British minor/industrial railways.
During the past year or so my objectives have become clearer American narrow gauge using rtr locos and stock in the garden with kit and scratchbuilt structures and Irish Broad and narrow gauge in 4mm GSR/early CIE chiefly kit and scratchbuilt locos, stock and structures with little place for the rtr models that I have collected in recent years.
All four tracks have now been laid in Waterford fiddle yard. Each track will hold twelve 20 foot wagons and a locomotive. Previously there were five tracks, three held eleven 20 foot wagons and a locomotive, the other two were even shorter. The yard tracks have enough finger room between them to make "fiddling" rolling stock on and off the lsyout easy. A long narrow shelf above the yard is planned to store surplus rolling stock. Before wiring started on the rebuilt section of Glen More my hand heald DC throttle died. The unit gave me over twenty years of service and will not be replaced, it's finally time to convert to DCC.
