4137 will be in service tommorow. It was at Hillcrest for around 1 year for a number of things. The most notable change is the new shiny paint job. The car also sports new style fleet numbering. Slightly smaller and narrower than existing fleet numbers on most cars. A number of cars had recieved the smaller but bolder numbers as well. So 4137 will support the third distinct font style now in service on the CLRV and ALRVs. 4177 also has this new font style.
Off the top of my head, Ill li
If it did have some high voltage power run through it, they're likely going to have to replace the LVPS and controller systems at the very least, and quite possibly most to all of the electronic systems on board the car.
