Really glad to hear IM was dealing with it honorably. Now I have to check my special run boxcar...which still has factory air. Ugh. I haven't seen this in current production in a long time. I've learned to accept/anticipate it in old Atlas/Rivarossi stuff, but it's like the measles returning....you think it was beat, but nooooo.... Having worked in ISO-XXXX environments, you get a vendor to certification, and then believe what they tell you and don't 'waste' money on periodic testing of inbound material or parts for quality, they have to have an plan in place and set control limits, recertify, all that. Oops. Yeah, about that.... Company I worked for before ended up closing an entire division due to warranty claims on defective material on a fully 'certified' supplier. Not coincidentally on the quality of the metal finishing. You forget that for most model railroad stuff, it's a more tangled multi-supply logistics chain that you can imagine, particularly for locomotives with motors and electronics. I'll bet you that the metal casting is at least a couple suppliers down. Hopefully Joe will chime in here on the boxcar frames, that's really unusual for them.
