About 30 years ago I downsized from OO to N mainly because I had become frustrated trying to fit a OO layout into a smallish room and with my very mixed results trying to scratch and kitbash Irish locos and stock.
The layout was a terminus-fiddle yard end to end with an intermdiate station, I was mainly interested in the contemporary operation on the Midland Section with Intercity passenger, Mail, Liner and traditional freight services.
The BoBos were based on Rivarassi SW1500 American Switchers, with new cabs and extended hoods, a 001 & 141 had plasticard bodies on Arnold and Rivarassi Chassis.
The photos are not great taken with an Instamatic Camera.
The terminus Duncormick was mounted on a 12" wide shelf on the front of the firebreast. Most of the buildings were scratchbuilt the station based on Foynes, a typical GSWR sawtooth loco shed and low relief buildings in the background from a sketch in one of Patrick Shaffery's books on Irish Architecture.
A bit fuzzy Rivarassi SW1500s with plasticard cabs, BR heating van kitbashed out of a pair of Lima Break ends. The Lima coaches are a touch narrower (1:160 Scale?) than the Minitrix coaches giving that typically passenger train Irish profile.
A move of house left no room for the railway and a move back to 4mm and some scratch buiding thanks to Tim Cramers series of drawings in Model Railways.
My first efforts in 21mm Midland 4-4-0 & 6 Wheeler. The loco was scratchbuilt in plasticard with Lima 4F tender drive, the measurements for both were taken directly off the drawings, unfortunately the coach was to a slightly larger scale.
The 4-4-0 again with what appears to be a GSWR cattle van, N Scale plank in the background coaches are Farish 4 wheelers. I am not sure if the loco was ever a runner I simply bored out the Lima final drive and axle bearings for the new 1/8" Mike Sharman axles, not a good idea
While they looked reasonably pretty at the time I hadnt mastered a running chassis and the 4mm models were all scrapped. I since fretted out a set of brass chassis and body parts for the 4-4-0 which is still in the scrap box along with the wheels and fittings, perhaps some day?
A year or two later I tried my hand at a Midland 2-4-0 in brass while it ran quite well the less said about the bodywork the better and it met the same fate as the 4-4-0.
