Having received this model, able to start the 'adjustments'. Relatively little work required, which is very welcome. No trouble with the 36" minimum radius curves on the running lines. And also will go around the 30" radius in some yards at slow speed, which is a bonus; and overall rides very smoothly in operation.
I really like this model: there's got to be a fictitious lined BR green example in my future, this will look good...
