KATO N Gauge V17 Double Track Slab Track Set Model Railway Rail Set 20-877

Run realistic subway trains! A new genre of double-track slab track has arrived for Unitrack rails. The slab track, originally used for double-track elevated railway lines, has been separated from the elevated frame and is now being sold as slab track commonly found in subways and tunnel sections. The track configuration is similar to that of a double-track line, consisting of straight sections based on 248mm gauge, curved sections with R414/381 superelevation (including approach tracks), newly established 62mm straight sections for ground use, and feeder tracks.
