For development of Exhibit A plans,

project managers and

designers are encouraged to familiarize themselves with the railroad company’s design standards, as well as TxDOT annotated exceptions, prior to design. While the railroad company does not formally accept these annotated exceptions, they are published to give TxDOT’s recommended practices

to designers

where a difference of opinion on certain guidelines exists. Many shortline railroad companies do not have established design guidelines.

Designers are

recommended to follow the BNSF/UPRR joint guidelines.

See the

RRD

website for railroad company design standards

and guidelines

. Additional design references are found in Chapter 14.
