Project Description 

PNR RailWorks crews are replacing power rail on the Expo Line. By early 2015, they had replaced about 40 kilometers (about 25 miles). 

Project Scope 
The PNR RailWorks crew of 35 people are replacing power rail on the Expo Line in three process-oriented teams with distinct roles:
 
First, the engineering team uses computer-aided design software to draft construction drawings that not only meet the criteria in the customer-supplied design drawings but also pre-determine the length of rail and the locations of other components.
 
Second, the preparation team cuts and drills rail and then sequences the rail and support components so that they are accessible in the correct order and free of any issues for the installation team. 
 
Finally, the installation team performs its tasks during a 6 1/2- hour overnight shift, removing old power rail and components and replacing them with the new material readied by the preparation team.
