It should be noted that the MTH NYC Mohawks are modeled as the late/final version of the engine with the one piece front air pump shield, the top check and the relocation of the sand dome. Dimensionally, compared with the dimensions of the prototype, they are either very close or exact, although MTH used 69-inch for the driving wheel dimensions on the L-4, which had 72-inch drivers. (An L-4 with a max of 3-inches of tire wear would be at 69-inches.) Of course, builders and super heater plates are also correct for each road number, and the hydro and hammer date and two letter location on the main reservoir is correct for the specific engine assignment for the date stenciled., and these dates and locations differ depending on the road number. Lettering and numbering are the correct size, font, and in the correct location on engine and tender.
MTH also did a great job with the differences in the NYC L-3 and L-4 Mohawk subclasses, especially the tenders. Coal and water capacity varied slightly among the L-3's and L-4's, and MTH correctly reproduced each specific capacity on the rear tender sheet. As built, the Central's L-4B's were the only NYC Mohawks with the "cistern tender", enabling water to be picked up from track pans at 80 mph. The MTH model of the L-4B tender differs from the L-3's and the L-4A and models this tender correctly. MTH models of the NYC Mohawk also include, as an extra piece, the piping along the bottom of the tender as an add on part for those who have layouts with wider radius, and MTH Mohawk models include the ATC pickup shoe on the third axle of the tender truck on the engineer's side of the locomotive.
