The past week I got bit by the MTH Railking Army flat cars, so I got a 4 pack of the Half-track from Mario's Trains, a single car each of the 6x6 and the 105mm Howitzer from Stockyard Express. Currently waiting to find the DUKW 353 but thank goodness York is in sight.
Also got a MTH PCC streetcar modeled for Cleveland, MTH Western Maryland fishbelly hopper, and a Lionel T&P boxcar.
