That's a reporting mark for "freight" service, just like JTSX, and CXST. Also, the "XMBT" name appears inside revenue CR engines as well, which meant that they were enroute to Boise for rehab.

Reporting Marks

Postby GP40MC1118 » Wed Oct 13, 2004 6:30 pm

MBTX is the official T reporting marks for commuter rail equipment.
Happened about two or three years ago.

XMBT was an improper reporting mark used by the MBTA way back
when. It has nothing to do with shipping equipment. The T had no
official reporting marks for years, then got MBA for a few years.
Apparently, they did not renew these and lost it to some other

BTW, the T bought 13 ex-Amtrak gondolas for its MW fleet in
August. Retain Amtrak orange paint and roadnumbers

I have also seen another set of initials stenciled on units that are heading west for overhauls. I beleive MPEX or something close to that. (only on loco's that will get a new paint job before returning.)

"X" has nothing to do with "freight service."

"X" means that the car is privately owned or for company service- like GATX- General American Tank Car Lines. This is why CSX's reporting mark is "CSXT"- otherwise they would have an illegal reporting mark symbolizing a private company and not a common carrier.

MBTX cars are just like Metro-North's MNCW and MNCX cars... they're company service cars.
