As pictured above, these 2011 models are available with either flat doors or Youngstown doors. All are equipped with FVM metal wheels and Micro-Trains body-mounted couplers.
Custom built by the B&O and the PRR, “Wagon Top” cars derived their nickname from the fact that their outside bracing resembles a covered wagon. The PRR’s car was meant to increase inside height dimensions for increased efficiencies whereas the B&O’s design came mostly out of the road’s ever evolving desire to save money wherever and whenever possible. The B&O’s design proved highly successful both in terms of providing a reliable car to transport goods as well as being a money saver (building cars in one's own shops being cheaper than buying somebody else's cars).
