    Hi Group...
    Just purchased a TRIX Big Boy (UP) and noticed that the set of rods on the front of one side that power the wheels have a tendancy to want to pop out of the transfer box.
    I purchased the engine from a respectible model railroad hobby shop here in CANADA so the wheels are definatly corrected for North American rails.
    The loco is in HO scale.
    Any suggestions would be greatly appreciated.
    thx ahead!

    I'm not familiar with this particular model, and without a picture, I'm uncertain as to what it is that you refer to as a "transfer box". I have seen on occasion where the piston rod will drop out of the cylinder on the backstroke: this is usually caused by the cylinder block being skewed on the frame, thereby moving the cylinder on one side closer to the drivers, and on the opposite side, farther away. If the piston rod isn't long enough, it will drop out on the latter side. The usual fix for this is to manually realign the cylinder block, then retighten the screw holding it. Could you please post a picture so that we can see where the problem is?
