I never had a proble with the trailing truck, I think for three reasons:
I rarely run in reverse
I have a minimum 8ft diameter curve:
The side play in the drivers (as discussed generally in the rigid chassis debate) causes the front end of the loco to push outwards under load. This exaggerates the problem with the leading pony truck, but conversely reduces the problem with the trailing tuck.
As an aside, I see what you mean with the copper boiler. Mine is in an alleged Nappa Valley colour scheme which is much more tasteful
Ah - ignore the fact that mine's now running on a different drive train

Mick, the same formula applies to both ends. Glad it worked out.
As Chuggs has noticed the problem is less on larger radii, obviously as the angle that the wheels attack the rail-head is less so it has less tendancy to climb it, but it must be loading the flanges and increasing wear significantly. In other words, you can get away with it somewhat.

trammayo said:Hi Bob - correcting the B to B, along with the other mods, was a significant factor. What I would like to know is this;- Is the loco a model of a prototype?
You do ask them don't you?
The only place really that the B2B could be a serious problem is through the check rails (points), the rest of the time if the other geometry is near enough correct it wouldn't be noticable.

Well somebody needed to pose the question
Yes it is the check rails and - as is the norm - one size does not fit all

Well, that's a bit of a surprise as there is much of the loco that is Bachmannesque, and the wheels are defintiely from that stable.
The B2B is governed by the length of the plastic tube.
The only trouble I had was the LGB R3 points - well documented (as well as my dislike of them)
I changed the driving mechanism because I wrecked the main driver bearings after about 4 real miles' running. Because the bearings also form the conectivity, I didn't lube them, but Electrolube would've been a wise choice :impatient:
As to a scale model - I don't think so; well not scale anyway. The cab is huge, and in standard form the boiler sits high. Also, unusually for a US loco, the firebox isn't in the cab, which is why you could hold a dance in there
Somewher I've got a picture of the cab with the fireman holding a log, but I seem to have mislaid it......................:thumbdown:

This is how a few of my drives finished up. The first video the loco was lowered around 10 mm.

I never understood what the rubber tubes were from the front of the cylinders to the valve chest - haven't seen too many of them on 1:1 phots, so I removed them

Right, so let's get on to the sound which apparently was rather variable.
Mine is loud and fantastic - it sounds like a loco pulling hard up through a cutting, the whistle whines every now and then, and in reverse there's a bell.
I only have standard Bachmann sound on the Mining Mogul (which is carp) and promise myself that I may do sound to my other locos one day.
But this is as good as it gets
