Re: [TramsDownUnder] Sydney Light rail

I attended both the previous incidents in Pitt St. I didn't see the Unimog at either of them, so I'd guess it is not equipped for this sort of incident.

The first approach was to try and drive the tram backwards from the other end. But that suspended section is not real good at telling the end module where it needs to go. All it did was increase its angle to the track.
The second approach was to use the ex-STA heavy duty Volvo tow truck to pull the set forward. But with the wheels embedded in the concrete oblique to the rails, that didn't work either.

Eventually, the heavy rail accident crew arrived in two trucks with all sorts of wizardry. I don't know where it is located, or how dispersed the crew members are, but it took about two hours to get there. The module was jacked up to get the wheels clear of the ground, and a series of skates placed underneath; the the car was dragged sideways with chains and hydraulic pullers back to the track and lowered. A quick checkover by the maintenance staff, and the trams were driven away. The second incident took 4 hours from reported occurrence to site clearance; the first may have been longer.

There didn't appear to have been any protracted electrical isolation, other than dropping the pans.

Sydney has a more than capable Unimog 'recovery truck' that probably is more than capable of pulling the tram back onto the track.

It's not the hardware, its the process.

I watch them attend a pantograph flip at Haymarket Christmas day last year. The crew were there pretty quickly - but took hours to 'secure the site' before they could actually start work. Once they got to actually working on the problem things moved pretty quickly. When I'd arrived the incident was already hours old and they handn't started work yet.

That car collision probably couldn't be touched till the police traffic accident investigation people come out and took their photos and measurements. Then the tram recovery crew are allowed to start work.

Was reported on TV news, both Channels 7 and 10. Trams at this location reported as held for three hours while rerailing took place.

There was another car accident derailment on Monday night which seems to have missed media attention.

Inbound tram 25 was hit by a car travelling east on King St and ended up straddling the outbound track. The railway accident unit attended, along with fire units from FRE and FRNSW.
