Train power line construction begins on N Line
Work to install OCS poles on N Line
The first of the foundations and poles along the North Metro Rail Line for the commuter train electric power lines are being installed between the Northglenn•112th and Eastlake•124th stations.
It's called the Overhead Catenary System or OCS.
Work to install poles for OCS on N
The OCS poles are located adjacent to the tracks and are essential to carrying the wires that energize commuter and light rail trains.
Each OCS pole has been designed for its specific location.
There are approximately 580 OCS poles along the first 13 miles of the North Metro Line. Each varies in height from 25 feet to 42.5 feet and they are weigh roughly 2,000 pounds.
The electrical system that runs along the OCS poles is intricate and required to run the trains throughout RTD's system.
The OCS poles hold messenger and contact wires that work together to distribute 25,000 volts of alternating current, specifically for commuter rail operation.
OCS poles and foundations are a big step in the progress of construction of the new rail line.
