8606 ran light night doing some rail drops in the city underground. It will also run tonight, tomorrow night and Thursday night. According to a facebook post they fitted it with a temporary pantograph which was overhauled last week and 2 others will be overhauled. At the moment, it's only fitted with a single pantograph although it seems there is no issue with it running like that.While I never set foot inside an 86cl I did work on many 46cl. The 46cl when in MU had to have only one Panto up in the metro areas inside the line borders, running LE they had only one panto up on singles and doubles, while on single loads, they had both up.
I was qualified for and worked them in the early mid 1990s .Thanks for that info. We never had more than 2 46 together on trains, I do recollect seeing triple in LE to Sydney yard though once they all had only one panto up, all up outside the borders on doubles but single had both up on trains. Its been a long time though since on them.
Going back a while but I think the restrictions were how many pans up and how much upward pressure they exerted on the contact wire . With two I think you could have both up and the main advantage of this was if you got panto bounce at speed they rarely both bounced
at the same time so the engine would generally not trip out (no volt relays) .
I can't remember the story with 3 but we always ran only one up with quads on Illawarra coal trains .
There were also power restrictions which limited the motor combinations you could run ie Series Parallel with no weak fields .
