Hi Everyone:
How do you deal with RR curve (chord definition) alignments in Carlson utilizing the input/edit centerline file ? Is there a way to set it up to station utilizing a chord definition in Carlson ? I have alot of centerline rail data utilizing spirals and simple curves and it is important that my stationing is on per their design for other future rail spur alignment tie-ins.
Thanks!

I don't have Carlson 2010 on my computer any longer but see if the control shown below (captured from Carlson Survey 2012) is available to you:

Depending on how well that software package handles your needs, you may or may not find my little curve calculator useful.
