Broad and normal and narrow gauge

Post by EnternalD »

I always had one question:
How does the broad of gauge affect train riding?
And how does train capability of carryng cargo is affected (on broad systems (imagine 2 and more meters broad gauge)) ?(

The broad gauge system of the GWR could run faster and smoother as the wheels would be on the outside of the stock. According to Wikipedia anyway.

As far as my knowledge goes on the subject I think the broad gauge system makes the train run faster and smoother. :)

Kind of correct, you get smoother riding, and generally faster (without quite as much associated wheel wear)* if you the wheels are larger. By position outside the carraige rather than beneath the wheels could be made larger and as such would give a smoother ride.
The main disadvantage of broad guage is that the corners have to be very shallow which is why most railways in mountainous areas are of a guage 1m or less. However a narrower guage doesn't necessarily mean lower speed, indeed in Australia (some correct me here,please) in Queensland (?) they have trains that run on metre-gauge that run at speed of up to 200kph.

*Kinda related to this is the world-record breaking TGV set that was fitted with larger wheels in order to attain the record breaking speed.

All else being equal, broad gauge trains are more stable. Speeds can be higher around the same radius curve since it takes more centripetal acceleration to move the center of mass outside the rail gauge. Also, a slow train on a superelevated curve wouldn't be as likely to tip to the inside of the curve. Radial steering trucks (bogies) would solve a lot of the problem of curvature on broad gauge lines.

Two meter rail gauge, with generous loading and moving structure gauges. . . Maybe in Camelot, or Shangri-La.

Yes, the Queensland Rail tilt train can run that fast, but in practice all the tracks are too shody with too many level crossings. by the way, it runs on 1'067 mm guage.
