OK, so I did the honorable thing and gave my positives, so now the gloves come off...
-FREEEEKIN' TTX or Trailer Train yellow 89-foot flats. Only Kato's release tactics (and by a razor thin close margin) exceeds the "What the hell" factor that not releasing these cars generates. Picking a post 2001 DODX scheme (which by the way was already available in a set) was a MUCH better idea for one of the first runner packs than TT/TTX. That ticked me off so much that I am hoping and praying Atlas will do their 89's in N so I never have to reward MTL's stupidity regarding this car.
-The $30 BN rotary-scheme triple hopper. OK, let's take one of the most ubiquitous freight cars that BN/BNSF ever owned--appearing in just about every unit coal train and most manifest trains in some capacity and a car that most BN/BNSF (and other modern) modelers would buy a dozen of without blinking--and we'll go ahead and charge $30 for it. Sorry MTL, but your car isn't THAT much better/not wrong-er than the Atlas version. When I can buy a 3-pack for what your single car with crappier paint costs, it's not a decision.
-Two words: ETCHED METAL
-Two more: LOW PROFILE
-Two more: CADILLAC SUCKS (* in the context of model railroading products...not trying to start an automotive thread here)
-Improve your dang couplers! It's been a gazillion years since the current design came out...find some new processes and materials and innovate again! Slinky-less travel is now en vogue. While you are at it, make them a little smaller and something resembling the real thing.
-I've been in model railroading for 30+ years now and have yet to have my ROW flood, nor have I had problems with dead cattle causing derailments. How 'bout lowering the ride height on your cars?
-Try doing some research every once in a while. I don't expect perfection, but when something is handed to you, or it is easier to do it right than screw it up, try doing it right the first time.
-Sell your trucks without wheels for us metal heads.
-Sell bulk packs with at least, say, a penny per wheel discount. Throw us a bone.
