HO Streetcar

[Green_Elite_Cab]

I don't know if it would interest you, but since you have Philadelphia PCCs on your layout,  there are a limited number of powered  IHP Kawasaki street-cars  left at the SEPTA store, which is around the corner from my job in Center City Philadelphia.  These are the cars that have been in use since 1981, and the cars are available in several paint schemes depending on the era.  



The drives are supposedly identical to that of the Bowser PCC (my streetcars are first-run dummies, before powered ones were offered),  but they might require some weight.  The models are going out of production due to a lack of interest, so I figure I'd mention it.    IHP used to offer all sorts of Philadelphia area trolleys in the form of resin shells but they are mostly discontinued. I believe IHP offer types some on their shapeways site.  

I am defining my minimum street width in two scenarios
1. Single track, two way street traffic
The sample is not bad (add yellow lines to protect the trolley lane) but there is no space for parking along the street. That is not realistic downtown anywhere in the US. The white board strips at the sides must be added as parking strips on at least one side.
2. Single track, one way street traffic
That is the absolute minimum (turn the white car around). Parking on both sides and one combined trolley and street traffic lane in the center.
Intersting study to get a balanced rail / street relation.

It definitely must have been like scenario 2 in the city.   I saw the old cobblestone streets and street car rails that pass by where I work several years ago when they were tearing up the road.    The street outside is pretty much exactly as wide as your photo.   Today, none of the street cars run above ground in the center portion of Philadelphia.  They run underground in tunnels  before emerging west of the city center.
