OK, here is my streetcar post. The goal here is to just show the mechanics of it.
The first hurdle to public transit, especially those of us that ride it infrequently, is we never know how much it will cost and how to pay for it. Modern transit systems like Portland's deal with this by posting easy to understand directions and using machines that take cash and credit cards.
Trimet MAX and bus ticket machine, with a validator to the left. These tickets are also valid on the streetcar:
Then you approach a stop. This is what a stop looks like from the sidewalk or rear side. This one is cluttered with newspaper racks and a bike rack:
Here is the same stop showing the catenary and support post:
Notice how the stop is a raised bump-out in the street:
Since they are located near intersections, they do not remove many parking spaces, yet they do not block traffic because the loading is fast. The loading is fast for two reasons: prepaying and several sets of wide doors at grade.
Here is a less cluttered stop. Notice how there is a step up on this side. Most of the stops have a step at one end and a slope at the other end:
Inside the small stop shelter, there is a map and digital display:
The digital display tells you the time until the next two trains. After looking at this you can decide if you want to run across the street and get a coffee. The displays were very accurate, and I think they track the trains with GPS. I find this function very helpful:
If the display is malfunctioning, or you are a few blocks away, and want to know when the next train comes, you can use this tracking number:
They also list several websites for further transit option info, including cars:
A streetcar approaching a stop:
The entry is level enough for people with walkers and strollers, but if you have a wheelchair, you can push a button and a small ramp pops out. It extends in a few seconds and retracts after the doors shut:
This streetcar is moving away from us, but the front and rear looks the same:
Here is a streetcar mixing in traffic:
Once inside the car, there is a large level area, then this stepped-up area at each end. In this shot you can see where the driver sits. He has his door open, and can keep an eye on things if he needs to, or he can shut the door:
Here is a shot of a typical crowd on the streetcar.
There were many people in wheelchairs or motorized carts, but I didn't get any pictures of them. If you didn't get your tickets outside, there is a machine inside, shown here on the right:

Here is a short video not by me, so you can hear it:
That is how it works. It is very low-barrier, easy to use and thus popular.
