Well, I have finally received mine, in the sense that I have arrived at where I had them delivered to.
A few points come to mind.
1, The brakes seem to be seized in the off position.
2, The ballast delivery gates are stuck shut - I was hoping to automate the brakes and the gates via DCC control.
3, There seems to have been little thought given to fitting smoke units which could be used to simulate the dust from filling operations.
Other than these points, they seem quite good - and the boxes are OK, too.
Keep up the good work.
