Gang,
Somehow I've managed to stumble into the digital edition of the January 2019 issue of Model Railroader (not sure how...) and on Page 26 is Jim Kelly's regular column "N Scale Insight."? The topic of his column for that issue is our old friend the A1G Whale-Belly Tank Car.? Jim's approach toward the car is more "What were they thinking?" but I'd counter that Roco's product for Atlas, released in 1970, had not been run before and hasn't been done since.? That's not the only A1G car that has that distinction.
Perhaps a Letter to the Editor is in order...
Cheers,
George
