I visited Imperial Train Co. recently. If you haven't heard already, they're doing another run of custom MTH Montour Railroad equipment. According to the clerk who was in on that day, MTH is doing three new items:
A caboose like the one in Imperial PA.
A Montour #76 SW9 (Bicentennial)
A Montour girder bridge
In addition, the shop still has a few of the Atlas hopper sets and PS-3 Mikados for sale.
