@RSJB18 posted:I just added this Williams PRR tanker to the fleet. Looks like NOS that was never out of the box.
After checking it over and lubing the axles, a shakedown run showed that the wheels didn't roll freely. The car was taken out of service with bad orders, and sent back to the shop. I popped the wheels out and ground down the axle points about 0.20mm which seems to have solved the problem.
I may change the trucks to a better set of sprung trucks. The originals are really cheapies.I also added an ounce of weight which put it right at NMRA standards.

Good looking tank car Bob. 
For truck replacements I use the MTH articulated coupler trucks that give more flexability in tighter turns. I use them on everything I have on the rails. I imagine there may be similar types out there.
Have fun sir .
