@Mark V. Spadaro posted:There is a fairly elusive Lionel NY Central Pacemaker freight set, with 3 Std. O Boxcars, with diecast frames, and a caboose. I don’t have the MPN for this set. Otherwise, this list is as complete as I have been able to find, as there is no readily available resource. If anyone knows of any other boxcars or reefers with a diecast frame, please add them here.
The above set is Lionel 6-17246. It is listed in the 1998 Lionel "Classic Trains" Volume II catalog.
In the same catalog are (2) more sets, the Union Pacific (6-21757) and Northern Pacific (6-11977). Both of these sets offered (2) boxcars with diecast frames. A boxcar and a reefer. I have the NP set, the Lionel #'s are 6-17243 and 6-17316. As you noted, the 17243 is on your list. The 17316 is a 40' reefer boxcar with a diecast frame.
Just trying to help out.
