• Traction power substations transform the voltage from 230kV to the appropriate voltage (25 kV). • Distribution of power along rail corridors via Overhead Contact System (OCS), feeders and gantries. • To ensure reliable power supply, switching stations and paralleling stations are needed.

Traction Power Substation (TPS) A facility that transforms the utility supply voltage from 230kV to 25kV for distribution to the trains via Overhead Contact System (OCS). Approximate minimum footprint required: 75m x 50m (plus access road).
Gantries The 25 kV feeder wires from the TPS will be connected to the OCS with the help of gantries. The main gantry (also referred to as the catenary feeding gantry) is the one parallel to the track. Traction Power Distribution What We’ve Done - Electrification

Feeder Routes Feeders are cables/wires that carry power from a Traction Power Facility to the OCS via gantries. These will be routed either aerially or underground in duct banks.
Feeder routes will be used where it is not possible/feasible to locate a TPS directly adjacent to Hydro One infrastructure, or where a TPS is not located in close proximity to the Metrolinx rail corridor. Overhead Contact System (OCS) What We’ve Done - Electrification • OCS is a series of overhead wires which supply electricity to the electric trains.

Vertical clearance In instances where overhead bridges do not meet the vertical clearance requirements for electrification engineering solutions being explored including: raise or replace the bridge, lowering the tracks, or modifying OCS to fit within the existing clearance / opening (if possible).
Other Bridge Modifications Minor bridge modifications (e.g., flash plates) will be required on some bridges to ensure that the electrification system passes safely underneath the bridge. Vegetation/Tree Removals What We’ve Done - Electrification • Vegetation/Tree Removal is required for the installation of the Overhead Contact First System round (OCS) of public and 25 meetingskV feeder routes held in February order to: / ○○ MinimizeMarch the 2016. risk of tree limbs falling on the track or overhead wires. ○○ AccommodateFinalizing variousa mandatory conceptual clearance zone design to secure elements, the safety of maintenancesuch as bridge workers modifications.when working in an electrified environment; ○○ Maintain the safety of our customers and neighbours.

Mitigation Measures to be considered: • Barrier designs that maintain views; • A design excellence process will review options for design treatments/options Bridge barrier example from New for enhancing the aesthetics of bridge Zealand barriers
Traction Power Facilities • Traction Power Facilities have potential to affect views within the surrounding area, particularly where vegetation/ tree clearing is required or where there are no obstructions. Many TPFs have minimal to no impact on visual landscape as they are located in Example of screening around TPF industrial areas.
Mitigation Measures to be considered • Where feasible, landscaping and/or screening may be considered around the facility if located in the vicinity of residential/sensitive areas.

• EMFs are strongest when closest to the source. As you move away from the source, the strength of the fields fades rapidly. • Based on the EMI/EMF assessment completed as part of the TPAP, no adverse EMI effects are anticipated due to the installation/operation of the electrified GO Transit system.
