Here’s anotherie clearly running on two rails
Two
tracks, on top of one rail.
No, two rails on a girder; in railway parlance the track is the supporting medium and the rails, one rail to a monorail track, 2 rails for a conventional track, 3 rails for rack railways and some electrified systems plus more for some oddities.
The girder is the "rail".
Sydney's monorail ran on one girder/beam.
Except in the depot where it ran on two rails, proving, as I said, that it was not a monorail.
No it did not. They were 2 flat surfaces that although separated were the same width (37 inches) as the single beam on track.
How they put them into the depot is irrelevant to their operation as a Straddle Beam Monorail on track.
Did you ever realise that all railway rails are flat on top, in fact wooden railway rails were very flat except for the railway that used trees for rails and left them round.
Of course the rails in the depot were the same gauge as the running surfaces on the beams, otherwise the trains would have fallen off.
Do you know when the current millennium started or were you brainwashed on that too?
As an aside, what do you think of a government that would licence a supposed passenger carrier as an amusement ride and keep the fact quiet so as not to adversely affect the paying patronage?
Now you're just being ridiculous. You want to draw out the dimensions of a full Class A 68kg rail?
Of course there is a top of the rail but for your information it's not flat it is slightly rounded.
So are wagon wheels & locomotive wheels. Flanges are angled/bevelled.
What happens to wagon wheels if they're excessively skidded? They get flat spots/burn marks that have machined out..... the same for the top of rails.
That’s a new rail, most rails are flat on top after some use.
"some use" is wear & tear & that is rectified with maintenance. Optimal performance is maintained with good wheel & rail surfacing.
You really have no idea - when they're too flat they're replaced or a Rail Grinding Machine goes over them & reshapes them.
Rollingstock wheels are replaced when to worn & the flange is considered "sharp".
Trains will derail going through points because of sharp flanges.
Locomotives & Electric Multiple Units are sent into a wheel lathe.
The contact between the wheel & rail is only a smaller area. That's why the wheel wears in the middle & on the flange(on curves) - curves which have auto graphite greasers to reduce wheel wear & squealing.
And in wet conditions all locomotives are fitted with sand boxes that drop sand onto the track to prevent wheel slip.
You are still wrong in all your pedantic arguing about what constitutes a monorail, a rail line or track.
Rubber tyre marks on a flat surface do not make it a rail.
As for trying to tell me what railways are all about -
no cigar.
