|
|
Hi all... I'm curious about the ratio of LEGO train wheel diameter to the distance between the rails on LEGO track. Is the LEGO ratio correct relative to typical prototypes? The diameter looks good to me on 6-wides but sometimes it seems too small (...) (19 years ago, 17-Apr-05, to lugnet.trains)

(...) Not in the slightest. Correct width, assuming standard gauge of 4' 8.5", should be 10 wide (or about 1 stud to 1 foot). LEGO train wheels on 10 wides don't look good, IMO. (...) I don't really make any distinctions between 6 wide and 8 wide. (...) (19 years ago, 18-Apr-05, to lugnet.trains, FTX)

(...) Standard gauge Track 4' 8 1/2" = 1435mm Lego track = 38mm Thus Lego track is about 1/37.8 scale Lego wheel = 18mm diameter At 1/37.8 scale this scales to be about 640mm = or 2' 2 3/4" In the UK at least a standard wagon (truck) wheel is in the (...) (19 years ago, 18-Apr-05, to lugnet.trains)

(...) The prototype measures from the inside edge, IIRC since rail cross sectional dimensions vary. I agree that the wheels are under-diameter in relation to track gauge (Working some US numbers: a typical US non low profile freight car wheel might (...) (19 years ago, 18-Apr-05, to lugnet.trains)

(...) IIRC the Dutch railways has changed the gauge from 1435mm to 1433mm. I don't know about other countries. It is still refered to as 1435mm, but the actual gauge can be slightly different from place to place. Another detail that has changed over (...) (19 years ago, 18-Apr-05, to lugnet.trains)

(...) In the UK the track gauge is 1435mm +5mm -2mm, but never less than 1435mm at switches and crossings. The gauge is also slightly wider on curves than on straight track. On double track, the two tracks tilt slightly away from each other. Mark (19 years ago, 19-Apr-05, to lugnet.trains)
