H Mick,
Your explanation has been most helpful! I never realised that the 5 in PC5 referred to the number of notches. From the first photo, a screen shot from the video, there are clearly 9 notches, thus making it a PCM9. Whether it is the railway or tramway version is not so important to know.
I’m not certain what the second photo shows. However in my commentary, one of the central pair of contacts in the first photo had suffered problems, as well as something in the left side of the second photo. There was copper dust inside. Also a magnet valve had shorted out. No wonder the second car had to push the first the last mile or so!

On one ride the PC control on a Brill car failed and I am wondering whether anybody knows what type was used on those Brills. It looked bigger than what is on a P. A photo from the video could be supplied.
