The trains in my Cowen's Corner Hobby Shop, a focal point of my layout, have stopped running. When the switch is thrown, the lights inside the shop dim, but there's no animation. If it's some type of jam I might be able to fix it if I could gain access to the mechanism. The bottom of the shop has numerous screws, but it's not obvious (to me) which to remove. Does anyone have any hints, or know of a service document, that shows how to open up the Hobby Shop mechanism?
Lionel has a replacement parts list for this accessory, but it doesn't show how to open it.
