This argument about RTR versus kit built is almost irrelevant to me as a 7mm modeller. There are some RTR locos about but few and far between so most of the locos that we run are kit built and usually have quite a bit of weight in them. I haven't yet found the limit of what my first working kit built loco can pull, a 3F from a modified George Norton kit, but it could easily handle a 22 wagon freight on Long Preston. 22 was the most that we ran though when we were testing we did run some at 35 wagons. The wagons were kit built from a mixture of white metal and plastic kits with an average weight of over 4 ozs. 22 was the limit we chose on aesthetic grounds so that we could see the train in the landscape. Brass coaches from the likes of PC and Janick often weigh in at well over a pound and my compound can handle 7 of them with ease. On Green Ayre as the fiddle yard is shorter freights tend to be about 18 wagons and passenger trains of 6 or 7 max.
However I do have a few RTR examples from over the pond. The market is different over there and this little thing appeared this year.
I think it weighs about 15 lbs and I dread to think what it's haulage capacity is. I can't actually run it anywhere apart from the fiddle yard. The hole in Ingleborough where it goes through the backscene is to small. However Rule 1 applies and perhaps I may be granted planning permission for an extension into to the garden.
