Recently I completed this exploded view illustration for the Toronto Transit Commission. The illustration is the Low Voltage Power Supply (LVPS) unit for the Articulated Light Rail Vehicle (ALRV). The streetcar receives a 600 volt from the overhead power line as it drives. It is the purpose of this LVPS unit to convert the 600 volts into 36 volts of usable power for certain items such as interior lights, certain devices and controls.
This illustration is incorporated into the TTC Training Department’s maintenance handbook which allows information to be better depicted for those learning how to fix and/or troubleshoot various components of the streetcars.
