At interlockings, such as CP-248, additional catenary bridges are being installed to provide better support for the more complex catenary construction at these locations. This can be seen where the catenary replacement is complete, such as CPs 229 and 266, among others.
There are also other locations away from interlockings where additional bridges are being installed to provide better support, or where the installation of a pull-off pole (used to center the wire on curves) would be unfeasible, such as at the Milford Station.
