rs-3 question

hey everyone just have a quick dumb question here… I just bought a atlas rs-3 loco and im trying to convert it to dcc. I have the decoder but im not sure how to get the shell off, the exploded diagram is not very helpful and I dont wanna break it. thanks in advance.

Remove the couplers, turn the unit upside down and look for little tabs. Sqeeze the shell where the tabs are and lift up. (make sure to remove any handrails that might be in the way)
