The Pipe Flat Car No. 2411 was created on the same frame as the No. 2419 Work Caboose and the frame number "2419-2" is in raised letters on the bottom of this car. This indicates that the work caboose was the initial production. In most cases the screw holes for the cab on the caboose have been filled in on these cars. There is no number on the sides, but the number "2411" is rubber-stamped on the bottom. This car is the same as No. 6411 except for the trucks.

This flat car was created on a GRAY painted die-cast frame with two brake wheels and end hand rails. It was equipped Type 3 staple-end trucks with electronic coil couplers. Most of these cars have "LIONEL LINES" rubber-stamped on the sides in serif lettering. There are three variations:

Variation A: Has three blackened pressed metal pipes that show lengthwise markings on the inside of the pipes. Reproductions of these pipes exist, but they are machined, and do not have these interior markings. 1946 production

Variation B: Has three 5/8 inch diameter by 7 inch long logs for a load. These logs have not been stained. 1947-48 production.

Variation C: Is identical to Variation B except sans-serif lettering is rubber-stamped on the sides.
