Those key system bridge units were frankly massive, Comparable to a two section articulated LRV from today minus the doors. I never saw an exact figure for the length. (Also they were coupled up to 3? 4?)

Length / длина: 110' 6'' or 33.68 meters.
Weight / вес: 137,625 pounds or 62 425.65 kg

A saw many photos of 3-car trains, which is effective 100 meters of tram. Let me know if you see photo of 4-car train.

Thanks: the VTA light rail trams are only 90 feet each. So the long bridge units were an interesting mix with the street traffic and street grid. The portland light rail is hemmed in by a small street grid, and not allowed to block perpendicular traffic, but I am not sure if people cared back then.

I will let you know if I see 4 cars.

In Sacramento in the 2000s the 4th car did not fit within the street grid extending beyond the standard city block. So when a train stopped at the station the 4th car would just block out the intersection behind the station by making it physically impossible for any other traffic to move. Which was effectively a safety measure ) I am sure this is what they did in the past throughout the US.

City block length restrictions is a headache of many US operations these days. In San Diego they had to order redesigned shorter cars from Siemens so 3-car trains would fit within the stops. Moreover, all curbs are extended at intersections thus making perpendicular streets narrower...

I am pretty sure the Key system only ran 3 cars of articulated units at a time after looking at a lot of old footage, pictures, they were only stored in this way when they were out of service.

This page just says they were up to 3

Even if it may have been technically possible, they would have almost never been operated that way. And only 4 survive today.
