Here are pictures looking from each end of the RailRax
Bottom row is all on type “B” scale trucks. Next row is is the same except to the left of the cobooses, cars are on tall type “D” trucks. The lone Santa Fe caboose on the 3rd shelf is also on tall trucks and is waiting for me to add the NYC & B&O tall truck cabooses that need to come out of set boxes. I do need to shuffle things a bit to squeeze in a long hunted for NKP flat car that came from the factory with no U posts. Still looking for the illusive red end boxcars at a price I am willing to pay
The rest of shelf 3 and most of the 4th shelf are 3/16 Sakai. One steam set is the Hutton Pacific, the other two are Hudson Pacific, one with the normal stamped steel trucks and couplers and one with the harder to find die cast truck and couplers. Also a Sakai diesel set that is missing the caboose. I’ll get a nice one some day to complete the boxed set.
