Amazing Pace for GO Transit
Operator Tim Dagenais stands in front of a tie remover/inserter used on the job for GO Transit. Besides the tie replacement, the scope of the project also involved removing and disposing of all old ties, a job that Operator Dan Springer helped to handle.
During a tie change-out job in Greater Toronto, ON, PNR RailWorks maintained such an impressive pace that customer GO Transit decided to up its order. And PNR RailWorks delivered.
Restricted to night and weekend work windows, a 26-person gang changed more than a third more ties than initially required over the duration of the project. And they did so during the originally allotted time frame of two and a half months.
The initial scope of the project involved changing 15,600 ties throughout the Oakville subdivision on main tracks 1, 2, and 3. Shutting down any one of the main lines on the extremely busy subdivision, running GO Transit, VIA Rail and CN Railway trains, was not an option.”
The initial plan was to change 325 ties per shift in between delays in GO, VIA and CN service. Once beginning the job, the crew discovered it would experience significant delays while working on such a busy subdivision. Mid-week work windows were limited to 6 hours, with 4.5 hours of productivity on average. Weekend work provided 8-hour work windows. Even with the erratic work windows, the crew was able to change significantly more ties per shift than planned. High productivity kept the project on schedule.
Based on this increased production, the scope of the project was revised to include additional ties within the same work period. By the time the project period had ended, the crew had changed 21,519 ties – nearly 38 percent more than initially planned, without a change in the initial time frame.
Effective organization and coordination between the working crew, protecting foremen and trains operating within the working limits allowed PNR RailWorks to average a surprisingly swift 550 ties per shift over the course of the project.
Besides the tie-change crew, a three-man crew surfaced track, and PNR RailWorks’ GO Transit Maintenance team performed constant flagging and crossing support. The scope of the project also involved removing and disposing of all old ties from the subdivision.
