Technical Specifications for Construction of Industrial Tracks

PDFs of Track Specifications are listed below, with associated diagrams listed under each PDF link.

These guidelines are provided by Union Pacific to assist our customers in the design and construction of industrial tracks. Facilities that involve unit or shuttle train operations may utilize more stringent standards. Union Pacific is committed to working with you to develop the most efficient, cost-effective rail plan to meet your transportation needs.

This technical manual and its drawings will be revised periodically. It is the responsibility of the User to update his/her copy with the most current information.

If you have any questions concerning this guideline or require further assistance, please contact the appropriate Manager-Industry and Public Projects.
