Hello

I want to remove the roof of the On30 railbus to change the decoder (install the dummy one).

The instructions refer to it as a snap-off roof.

I've tried a moderate amount of force so far, but nothing is coming apart.  Before I try and pry it apart with a knife or screwdriver, does anyone have any tips?  eg where are the "snaps"?  Where is the best place to insert a "pry-bar"?
