Here is a Western Maryland GP7 I bought a couple months ago. It is a Lionel Legacy engine with the WM “Highspeed” lettering (corrected, actually “Speed Lettering”). It was one of eight Geep 7s the WM owned. They were without dynamic brakes.
I found the matching Lionel caboose recently. It is a typical WM Northeast style caboose with the same style lettering.
