Light-rail for mass transit was brought to my city in 1985. At that time there was plenty of infrastructure in place already, so much of the track is either tunneled or on an elevated guideway. When the new transit system was introduced, it was so futuristic. Almost the entire system is computer-controlled, eliminating the ticket vendor, door men and even the conductor. Who knew the ultramodern future would be so impersonal?
They even thought up a neat way to automate the door closure safety by using a pressure-sensitive strip along the edge of the door, ensuring no one gets their arms caught in the doors and lopped of at the elbow at the first approaching tunnel. Bummer, some people ruin all the fun.
Luckily, the door safety mechanism can be overcome easily enough to allow for a camera to be located outside the train and take some unique footage.
This mount uses the doors to hold a camera outside of the train without interfering with the pressure-sensitive safety-strip on the doors. The mount is physically stuck when the doors are closed and requires the doors to open in order to be released.

Tampering with private property is an offense.
Overcoming safety devices on public transit is an offense.
Projectiles or objects affixed to fast moving vehicles poses a potentially fatal hazard.
DO NOT ATTEMPT.
Enough talk...train camera!
