The LRT trains have rubber tyres,but why it is better than MRT using steel wheels on steel rails>?

Question

By the way,what does the ancronym LRT stands for?

Answer 1

There is a type of LRT which is closer to a guided bus.  They use a dedicated guideway and they roll on rubber tires.  There is some sort of guide rail to guide the vehicles and also supply electricity.  Typically airport "people movers" are like this.  Monorails also usually run on rubber tires as well, though the guideway is much more prominent, obviously.

I tend to call these things "people movers", though some people movers are regular steel wheel on steel rail.

I wouldn't call it "better".  I'd call them "cheaper".   Note most such lines are fairly small operations.

Answer 2

I'm sorry but I don't know what either of the acronyms mean, but I assume both are metro lines, parts of which may be underground. Which is the reason for the rubber tyres. They are much quieter than steel wheels on steel rails. This idea was first tried on the Paris Metro and lines 1, 4, 6, 11, & 14 are so equipped.

Later. in view of other answers, I would point out that trains equipped with rubber tyres do have flanges, projecting lower than those tyres, to keep them on the rails. And, incidentally, all railway wheels have tyres - it's just that they are usually made of steel.

Answer 3

steel wheels offer less rolling resistance...

Answer 4

I don't think so  because all the train uses the steel wheel if the train use the tyre rubber wheel that's verry dangerous. The railways is steel so the wheel can get  abration that made by trubber

Answer 5

For LRT (Lite Rail Trains) they do have a rubber wrap, but it is smashed in between a steel wheel and a steel wrap.  The rubber helps absorbt the shock from the ride.
