He did eventually fix this, but I had to run for my tram and I didn't get the shot. Still, I like this as sort of a "railway workers at work" shot.

Sometimes, though, it doesn't work....

Most of the tram tracks in Prague have rubber sealing gaskets alongside of the rails, I assume to keep them from rusting in half or getting damaged by frost action. This machine is designed to install the gaskets quickly and accurately.
