Flange bearing crossing speed

Hello,

I am Naveen, uni student working on investigation of speed over the flange bearing crossings. Most standards state its 15 kmph but do they have any analysis backing up or is it jus a conservative speed to keep it on track.

Thank you,
Naveen.

Hi Naveen, and welcome to the forum.

I don't know exactly what the definition of a flange bearing crossing is, but here in the UK, 15 MPH is the default speed of turnouts and crossings. That's another way of saying that if a crossing doesn't have speed board, the driver must take it at 15 mph or less.

Hope this helps, BW

G'day Naveen and BW,
Yes, I was likewise bamboozled by the term.
But, there is some info re flange bearing frogs at Wikileaks.
https://www.google.com/url?sa=t&rct=...rAs7hZzocW-pmE
And if that link works, a PDF file apparently details the H type crossing.
I haven't downloaded the PDF, so don't know exactly what it details.
Steve.
