I am trying to find out the specs on the vintage 1511 9" straight track, thanks
what specs do you need? 9" straights haven't changed much over the years, and they were pretty much all interchangeable between makers until the roadbed style track came out.....
in this case i'd say depending on when it was made. it was either brass or steel rail. brass was used in the 1970s, steel later. for the dimensions, go to any hobbytown, pick up a loose piece of atlas 9" straight track from the bin and measure it.
Gauge, scale and width, thanks
9" straights are a standard size for HO scale, standard guage. afaik they aren't a standard size in any other scale. width over the ends of the crossties should be about 1 1/4 or 1 1/8 inches.
Nine inch straights are pretty much going to be HO, so the HO track gauges are:
HO Track Gauge: Actual Size
Standard (4' 8-1/2"): 16.5mm/0.65in
HOn3-1/2 (3' 6")/HOm (1m): 12mm/0.472in
(Commercially available TT scale track often used for this)
HOn3 (3'): 10.5mm/0.413in
HOn30/HOn2-1/2 (2' 6") 9mm
(Commercially available N scale track generally used, as well as for HOe less than meter gauge narrow gauges)
