Expand an M1 or M2 master set with the UNITRACK V5-PC Inner Double-Track Endless Set. This N scale track set uses PC concrete-sleeper track to create a realistic modern double-track layout.
Concrete sleepers became widespread from the mid-1950s and remain common on conventional ballasted track. The lower ballast surface compared with double-track sections creates a natural recessed appearance, while additional ballast can be used to model high-standard track.
