By the time I left SATS in 1986 they were looking at replacing the platform clocks with digital ones, but I don’t know if that ever happened. Although, the clocks I saw on the platform in 2010 looked very much like the ones I used to set back in 1985/6. Looking at the infrastructure today, after last seeing it in 1986, I can just imagine what Barney (seriously nasty Tech Supt in the Johannesburg Telecoms Depot) would have said about the current state of affairs. Probably rolling in his grave.
Don’t even get me started on station clocks…. When I qualified as a telecoms sparky one of my duties were the station clocks on Germiston Station, these were stepped by means of a pulse every 30 seconds that originated from the master clock in the exchange. Each platform had a double faced one, usually close to the stairs (this is 1985 btw), every morning when I arrived from Johannesburg by train I used to check the clock against my watch to see if it was running fast or slow, and when I went to the depot would check 2 faces of the tower clock on the station building.
The tower clock was a different ballgame, this was situated in a tower on top of the roof and was accessed via a trapdoor that led down a rickety ladder into a passage below. If my memory serves me right there was one mechanism that drove all 4 faces via a gearbox. But setting the time was another story altogether. Theoretically they should all have been showing the same time, but because of wear and tear in the hands and shafts, as the minute hand rose from 6 -12 the face would loose time, and as the hands fell between 12 and 6 the face would gain time (it’s called gravity). Each face was more prone to this than the other and we tried our best to find a way to prevent the hands from doing it but the whole mechanism was worn. You could also cheat a bit by physically moving a hand to try make the time more accurate but this could only be done from outside the tower. If we removed the hands or one face needed to be removed we then had to climb onto the station roof and blank that face off. There was a rusty iron ladder on the one side that gave us access to the ledge around the tower and a rusty chain that was to prevent us falling off. That crummy clock was one of my bugbears because the tech supervisor used to catch the train too and would check the clocks when he arrived and I would get a call logged to go sort them out.
You can see the white painted external ladder and the chains in the photograph below, you can also see the faces are showing different times. Sigh. All my hard graft for nothing.
