The Baby Ruth Box Car No. X4454 was issued in 1948 and 1949 as part of the "Electronic Set." Each of the cars in this set, including this one, had a radio frequency receiver on them that would allow them to be uncoupled anywhere WITHOUT the use of a UCS track section. The color of the decals on these cars determined which button to push on the ECU-1 Transmitter to uncouple the car. This box car has a BROWN decal with a Lionel "L" that reads "ELECTRONIC CONTROL" and was located between the first and second row of rivets to the left side of the car.
Created on an ORANGE painted body that has BLACK heat-stamped lettering, staple-end trucks with electronic coil couplers. Note that the identification number on the car is X4454 but only the number 4454 appears on the box. There are two variations:
Variation A: BROWN painted doors with Type 3a trucks.
Variation B: Chemically blackened doors with Type 3b trucks.
