Mornin’, Lorna - tac here over in UK having just delivered mrs tac to the airport on her way to stay with her cousin in southern Spain - hence the early bird comms.
I have a bunch of each, Bachmann and AccuCraft, electric and steam but can offer direct comparisons with only two - my AccuCraft K27 and the Bachmann version at 1/5th the price.
As can be seen on Youtube, for some unnacountable reason, they both run at precisely the same speeds hauling a long double-header, something they should not do, given the alleged disparity in the motors, but THEY don’t know that, and do it anyhow.
When we bought my metal K27 there was nothing else in the same correct scale, and it was not a bargain here in yUK at almost $4500. The Bachmann plastic version, however, has a bit more detail, and cost only £650 here, but with a fluctuating exchange rate it worked out at about 20-22% the cost of the AccuCraft version. It is, without any doubt, the most bang for your buck of ANY large-scale model on earth. Bought because it had the green boiler, we love it to bits and run it as much as anything else. To compare it with the AccuCraft model is a facile exercise, they are plainly in a different purchasing market, but if it had been around back in 2000, then I wouldn’t have invested my pension in the AccuCraft version, for sure.
Just to see what else is in the toy cupboard, we also have -
Bachmann
Two two-truck Shays with metal trucks - converted on disintegration of the original trucks, after that, no problems of any kind.
Two three-truck Shays - no problems of any kind.
Heisler - ditto.
Climax - ditto
Connie - just replaced the gear after almost ten years.
Annie, one of the very first - no problems of any kind.
K27 - almost three years old - ditto
AccuCraft Steam
Three-cylinder Shay - misaligned truck bolsters on receipt - fixed, and a couple of additions - otherwise no problems and nine years old. A Youtube star.
Gauge 1 Royal Hudson - way too many problems out of the box to list, but fixed, at considerable expense here in UK after parts sent to me free by Cliff Luscher in Union City - figure about $1000-worth. A Youtube star.
16mm Scale NG/G16 Beyer-Garratt - needed converting to ensure effective steaming, at my expense. It was the prototype for the ‘fixes’ on the second and third run of this rare loco, and runs beautifully - tons of it on Youtube.
16mm Welshpool & Llanfair Rwy 0-6-0 - a star runner out of the box and on Youtube.
16mm ‘Edrig’ - same again.
AccuCraft electric K27 - getting VERY heavy now that I’m getting old, but a very beautiful model that I jus love to watch and to listen to - full Sierra Soundtraxx digital sound system with shovelling fireman, Alumite greaser action and all the sounds you could wish for.
Many of us here have identical or not dissimilar experiences with comparatively high-dollar models, although moving up another gear in spending, my one Aster model has NEVER give nany grief of any kind. Your chances are better these days, as the latest tranche of steamers from AccuCraft, especially the smaller ones, are greatr runners.
One point here - you blithely talk about a ‘small track of 150 feet by 75’. That is NOT a small track by any standards, and will need some thinking about it you intend to run electrically-powered models of any size with reasonable consists behind them. You also mention curves ‘no less than ten feet in diameter’ - take an old man’s advice and make those curves as big as possible - on a track the size that you are contemplating, 16 or even 20 foot curves would be quite usual, especially if you ever have a guest running day and some klutz turns up with a USA Trains Big Boy…trust me, you can NEVER have too big a radius curve.
As for the means of powering this LARGE layout of yours, you’ll need to address that little problem separately, unless, of course, you intend to go over to battery power and r/c.
But whatever you need to know, somebody here has done it before, that you can bet on.
Best wishes and welcome again.
