yes, that did it. Thanks.

I recently pulled an On30 set out of storage from 4 or 5 yrs. I want to check lube before running 2-6-0 locomotive but cannot quite remember how to remove top shell.

I know to pull back on the plastic tab on the rear, and the top shell moves upward about 3/16" at the rear, but the front under the smoke stack isn't moving.  I did slide the two wires aside from the front platform to the body.

Can someone remind me is there a screw somewhere hidden that's holding things down.  I tried removing the bottom screw between the pistons but that didn't seem to have any effect.

Thanks for any help,  jtx
