Unscrewing MTH Subway Shell

I might also take them to a LHS.

A head that fits properly and you remove.  Some can me tight.  If you need to get in you have to remove them.  If the post breaks, MTH has repair part to fix.  G

I have 2 Proto 1 MTH subways, and want to take off the shell of the power units so I can remove the original battery and replace it with a BCR.

To take off the shell, one needs to unscrew several Phillip's screws. The problem is that these screws are in very tight. I tried to remove one screw in each power unit, but could not do so, even though I have several Phillips screwdrivers of different sizes. I did not want to force it too much for fear that I might strip the head of the Phillips screw.

What do you recommend to remove these screws? Is there a particular Phillips screwdriver and size screwdriver that you recommend?

I was thinking of taking these subway power units to a store like Home Depot to get their advice.

Hi Arnold,

You may have trouble with the Phillips screwdrivers you currently have.  May I suggest you search for a set of JIS Phillips screwdrivers on eBay.  JIS is Japanese Industrial Standard.  These are commonly used in the orient.  The tip angles are different.  Here's the ones I bought and they do make a difference.

Thank you Lou.

I went to Lowes today, and found a Sears Craftsman Phillip's screwdriver, that unscrews the MTH Phillip's screws that holds the shells for the MTH subway power units in place. The stem of the screwdriver is 10 inches long. It cost 9 dollars and works great. Arnold
