The Micro Engineering 17-055 is a 33-piece bundle of N mainline / HO branchline scale Code 55 (non-weathered (bright nickel-silver)) bulk rail — 3-foot lengths, 99′ total per bundle. Code 55 serves double duty — modern N scale mainline rail and HO scale branchline / sidings.About bulk rail: Bulk rail is sold without ties — for handlaid track, custom turnout/crossover work, or repair / spare-rail stock. Spike it onto your own wood / PC-board / plastic ties using the Code-appropriate spikes and tie plates.About Micro Engineering Flex-Trak: Micro Engineering is the gold standard for prototypical fine-scale track among serious modellers. Distinguishing features — scale-size moulded ties, tie plates, and spike heads (real spike geometry, visible at viewing distance) and irregular tie spacing that matches real-railroad practice (uniform-spaced model track instantly reads as "model"; ME's variation reads as "real"). Natural brown tie colour, nickel-silver rail.
