I’ve been wondering: what were common rail sizes on three foot narrow gauge lines (around the turn of the century or 1880’s, etc.)?
Probably the most common would have been in the 30 to 35 lb/yd range. Of course, it depends on the railroad. One of the touted benefits of narrow gauge railroads was low first cost, so some railroads took that to extremes and used as light of a rail as possible, with at least one example using 12 lb rail! Others used “strap” rail as a cost saving measure - wood stringers faced with a metal strap on the top for wear resistance. First cost was also reduced by spacing the ties further apart and using little or no ballast. Again, it depends on the railroad. However, if a narrow gauge line was successful, the increased traffic along with larger locomotives often dictated relaying the track with larger rail in the 50 to 70 lb range. More information can be found in George W. Hamilton’s book “American Narrow Gauge Railroads” - it is a must for any narrow gauge fan!

DRGW was using 30,35 & 45# as late as 1903. The two survivors (D&SNG plus C&T) have been trying for years to upgrade to salvaged 85# rail since they spun off as part of the sale.
