Before I break something trying to remove the cab of the Atlas Alco RS-1 locomotive, I want to ask those who have experience. It appears from the parts list that came in the box from Atlas, that I need to remove the grab rails from the cab, remove the cab, and then the locomotive top half in order to install a decoder. It also appears that the top half of the locomotive has four tabs, one on each lower corner that must be disengaged before the top can be removed. I assume that you must gently squeeze the lower part of the top on each side and pull up in order to remove the top?
