MTH Texas and Pacific 4-8-2 and passenger cars

"...but I really can’t comment on its authenticity, as the post WW-2 passenger blue color schemes are not my favorite. Of course it still has the coal tender...."

This model's authenticity is non-existent, except maybe for the paint.

Not quite:  there WAS an NYC Mohawk painted in that scheme in a museum in Texas.  It replaced an authentic T&P loco whose fate escapes me at the moment.  MTH (and Lionel before) were not responsible for creating the fraud, just perpetuating it.

Yes that engine has been described as a yankee visitor wearing a ten-gallon hat. T&P had presented Dallas with 2-10-4 638 and Fort Worth was gifted with 610. 638 was badly vandalized and the indignant T&P management summarily scrapped it. The TP later regretted it and bought the hapless Mohawk from NYC. It was displayed at Fair Park in the railroad Museum and later repainted as an NYC. I’ll need to do some checking it may be in Frisco which Is the Dallas suburb that now has that collection. When I saw it I think it was painted in the traditional scheme not the passenger blue. Truthfully Fort Worth’s 610 wasn’t treated much better; it had the gauges smashed and was sitting with the boiler jacket rusting  and asbestos lagging hanging out. A dedicated band of people cleaned it up and rebuilt it so that it could pull the American Freedom Train in 1976. After a stint with the Southern  Rwy it now resides in an engine house at the Texas State Railroad, not running but could be.
