Leveraging the patented Aurora Xi®  inspection data and a patent pending guidance system, Aurora Tie Marking automates the process of marking crossties that have been designated for replacement in advance of crosstie renewal projects. The guidance technology, using the Aurora collection software, works in near-real time to identify the appropriate tie and activates the marking system as it passes directly over the tie.

This hyrail-truck based platform is equipped with a paint spraying system mounted at the rear of the truck. Aurora Tie Marking is capable of marking ties at speeds up to 8 mph and can paint up to four marks per tie, which allows for jobs to be completed faster, more efficiently and safely.
