A light in the signal box has been added that can be connected to the accessory terminal on controller.  This can easily be removed with little or no visible residue (wire route can be seen in picture).

Some minor repairs:-

* The stairs have been glued

* One of the chimneys has come loose (not broken).  Will be superglued back into place prior to shipping.

Stairs will remain separate from building for shipping - buyer will need to glue locally.
