Intermountain has sent out the following in their IRC Modelers Club Info email for March. I can't wait to hear what their next car will be:
Z SCALE CYLINDRICAL HOPPER CAR
We are projecting August as the delivery month for the first releases of the Z scale cylindrical hopper car. Our production quantities contain some “slack” so if you have any late reservations please submit them. Our second Z scale car is nearly completed as well and will be announced within the next three or four months.
