L2/L3 down in Sydney

[TP]

L2/L3 services north of Central have stopped this morning due to wires down at Haymarket. Also flipped pantos on two trams.

Services resumed at 16:00 after 2239+2240 were split and towed away using 2259+2260.

The overhead didn't actually come down. It appears a bridle wire came off as a outbound tram 39+40 turned off George Street. Looks like 39 made it past, but 40's pantograph hit the dropper arms and flipped. It then hit the cross arm of the next pole and bent the cross arm and snapped the parafil contact wire support. It appears to me that this probably caused the contact wire to move so far to the side that 39's pantograph over reached and got the horns stuck ABOVE the contact wire, so it also 'flipped'.

As part of the recovery they amputated 40's pantograph just above the knuckle as there was no way they could flip the thing back to stow it. They managed to fold 39s pantograph up and tied it down. Both are probably for the scrap bin.

The fallen wire was coiled up near one of the poles and near where pedestrians could walk. It didn't look broken, it looks like it unscrewed itself. There must have been some residual twist in the parafil and after the lock nut came lose, it slowly unscrewed itself.

I took about 50 photos and some video of various tasks the crew did to recover the mess. Including observing the Citadis 305 coupling procedure.

Can’t blame the APS this time - damn.

Apparently the L1 was terminating at Convention while this was happening, and without knowing any better I speculated the problem was at the George/Hay crossing or the  junction wires, not as far from Hay St as the curve off George St.

Looks like a bit more overhead sectioning is in order so this interference to working on one line when the other has a problem can be eliminated.

Not that I expect anything will change.

There is. I saw trams moving on the L1 while safety earths were on the track/overheat at George/Rawson.

If they stopped L1 that would have been only the initial panic when the emergency call when out. Once the incident was localized, L1 would have resumed.

What I didn't manage to do is get a photo of a tram crossing George street behind the pair of Citadis stabled in the middle of George Street, but I certainly saw it.

Not that I expect anything will change.

Fair enough then.

When I first heard of it I visualised a pair of Citadis with flipped pans blocking the L1 tracks and wire on both lines down.
