Narrow Gauge Railroad?

[Bolo42]

Any chance of adding russian 750mm narrow gauge trains for industrial development?

Here we have a few other shots with same loco class (Lxd2) but on different railroad pulling standard gauge cars

Nice write-up MichiDem.

If I may add, the Standard Gauge is an English Gauge, and it is derived directly from the Roman Chariots, that were the approximate width of a horse’s posterior.

Well - that's just a theory, but just like with the "let's have wider gauge to prevent invasions" is just a myth
We could only ask Stephenson why he choose 1435mm

Stephenson did not choose the gauge. The gauge already existed. He built his first railway at 4' 8" because they already had carriages for that gauge that he had to use at the colliery at Killingworth. He then went on to the Stockton and Darlington Railway which used the same gauge. He later added half on inch of play to allow for better curve-performance when he built the Liverpool and Manchester Railway. The Gauge Act, an act of law, was passed to standardize the gauges. The gauge with the maximum usage was picked, which was 4’ 8½“. That is how the name came about as Standard Gauge. The pertinent question is, is it true that most of the existing tracks, although not exactly the same gauge, and were approximately the size of the horse drawn carriage? The answer is not so much of a myth.

Narrow Gauge is typically used in mountain railways, and it should be able to handle steeper gradient than Broad Gauge.

That would be an additional option of narrow gauge railway - mountain rack railway (https://en.wikipedia.org/wiki/Rack_railway).
This would be a bit more expensive to build than normal narrow gauge, but cheaper than standart. Also would require engines equiped for this. But would offer steeper tracks.

You are correct that rack system can allow for greater gradient. From the point of view of physics, the gauge should not dictate the adhesion based gradient. It just happens that narrow gauge routes tend to be in the mountains and tend to have a greater gradient, even if no rack system is used.

@michdem thats awesome I'll check the videos out just as soon as I have proper internet!

As a matter of fact there are normal gauge rack railways. Narrow gauge is often used in mountains because you need sharper turns.
