Piggybacking off the container related request I made earlier, some 1980s intermodal prototypes are still underrepresented in Trainz.
Trinity/Pullman Standard Backpacker (This version by ScaleTrains represents the original version of 5 40' wells.) TTX class RWG50, DTTX 64000-64070. There was a version of the Backpacker that had 2 40' end wells, and three 48' wells with 125-ton trucks, TTX class RWG52, DTTX 74000-74116.
Original Backpacker.
74000-series Backpacker A and E wells showing the difference between the end and middle well lengths.
Thrall Lo Pac 2000/Lo Pac-I 40' 5 unit well cars. Adapted from the Budd/Transit America Lo Pac 2000 prototype, initially used in large quantities by APL beginning from December 1983. Some carried generators for refrigerated containers. APL - APLX reporting marks, came in blue and red colors. TTX - DTTX 62000 number series, TTX Class TWG50.
There was also a less common variant of 2 40’ end wells with three 45’ middle wells, only TTX and APL rostered these with APL having 87 sets, APLX 4500-4586. TTX classed theirs in the TWG50F with 25 sets.
Thrall Lo Pac-II. There were a few variations of these. The most common configurations were 2 40’ end wells with three 48’ middle wells and 5 48’ wells. TTX had these in TTX Classes TWG50G/K/L, TWG52 (DTTX 72000-72151 72182-72321), and TWG52A/B (72152-72181, 72322-72882). The Santa Fe rostered 100 sets of the 40-48-48-48-40 version in their DS-6 class, SFLC 254100-254199.
