This may have been asked but the little loop on the streetcar alignment where it turns onto Central Avenue, is that to serve an institution or to avoid an at grade crossing with the CSX on Central. If it is because of the railroad crossing, are streetcars not allowed to cross an active freight line at grade level, is it a request by CSX, or is it a safety descion made by the city?
I believe there is only one place in the US, somewhere in Philadelphia, where a streetcar line crosses a mainline railroad at-grade. Diamonds, the metal pieces that join the rails from the four directions, have to be custom-manufactured. They also wear quickly and need to be replaced often (far more often than rails) and are therefore expensive to maintain.
