Railway Tracks - Allowable Minimum Transverse Slope

[Rob2004]

Is there any Allowable Minimum Transverse Slope between the two Railway Tracks. An existing pair of railway tracks are crossing a roadway whose longitudinal slope is 1.07%.

Do we have to flatten out the roadway where the tracks meet? Or could we go ahead and have a gentle transverse slope to adjust grades?

Thanks for your views.

Never mind. The Tracks are on a Horizontal Curve. Hence Superelevation covers for about 3.5 cms of grade difference. The rest 1.0 cms can be adjusted out in the field. Anyways, please answer this.

What is the ABSOLUTE decimal precision that can be implemented out in the FIELD? On the computer, I know we go for 3 to 4 decimal places. However, we wont be so accurate in teh field. So, for Iperial/Metric, what tolerances do you think is acceptable?

That would depend on the design speed.
