Greetings from across the Atlantic - I'm a US-based HO modeller, with a long-time secondary interest in British steam. Even managed to catch 60103 in full scale @ Paddington on a recent holiday to London; it was the highlight of the trip for my son as well.
That has inspired me to grab a FS set from Hornby in their new TT:120 range, with the goal of building a small exhibition-style layout that can fit on a table top, and be fit under a bed or similar when not in use.
Continuous running is a requirement to keep my son's interest (and I don't mind a nice railfan myself TBH), so roundy-round it is.
I thought the Hornby TT:120 trackmat plan based on a R3/R2 double-track loop wasn't horrible, but I have a touch more room (3'x5') and thought I could add a bit more operational interest and fix some of the design challenges (facing points, lack of trailing crossovers). Top plan is the original Hornby TT:120 plan, bottom plan is my modifications.
The concept is that the bottom of the revised plan will have a through passenger terminal good for 4-5 coaches, and the trailing points off to the engine shed @ right. The top half of the loop will represent the freight area, with a goods shed, coal yard and possibly industry (gasworks maybe?) on the various sidings. I *tried* to respect the fact that UK railways severely disliked facing points on the main, and added a second trailing crossover between the up and down mains to make a sizable passing loop. The left hand curve and central area of the layout will incorporate some kind of scenic block/tunnel arrangement to disguise the loop and increase the credibility at least a bit.
Very open to comments/suggestions on ways to improve the plan, without giving up on continuous running, the scale, or the basic size of the base.
Cheers,
-Paul
