Z Class Trolley Pole Hole

I'm curious as to the "patch cover" on the front of the Z Class trams, covering the place where the winding mechanism was for the trolley poles. This has had an oval cover placed over it.

I recently saw a photo on VICSIG of a Z Class tram that had the front end destroyed. Just wondering when it is rebuilt, will they do a solid front, or will they reinstate that old cover as well?

Our probably depends on what spare parts they have. If they have aprons that were designed to be fitted with retrievers then the front will be replaced pretty much as is. If they don't have parts and have to fabricate new ones out probably won't have a patch for non-existent trolley retrieves. Just have to wait and see, but my guess is that it will look the same after repairs.

That is some serious damage. Given the tram's class and age, wouldn't it be a candidate for write-off rather than repair?

It's not that serious. It shouldn't need to be a write-off when it's not that costly to repair the front.

Not necessarily, both Z3 156 and Z3 180 received comparable amounts of damage and were repaired.

I was just thinking that with the E class coming into service, and it seems as replacements for older rolling stock, the way to retire older stock would be on the basis of as-is condition. Accident victims can be a source of parts for others of their class. But if it can be / is going to be repaired, I am not complaining...

It's probably going to come down to an engineering assessment of the frame damage. The the frame is still straight, put a new front on. If the frame has bent any where past the door, spare parts.
It's a Z3, so they will be tending more to keep than scrap.

The front is a fibreglass moulding. They probably have some spares 'in stock' and if they didn't, they probably have a mould some where for making more. The mould probably has the rope-keeper mounts in it, so even freshly cast fronts will still have the reel mounts. It wouldn't be worth the trouble to re-work the mould.

Several years on and the oval covering the tram's former mammary glands still exists, even after coming out fresh from the life extension project. What I find weird though is the fact that A class trams still have them, particularly the A2 class which were designed with pantographs from the beginning. Why would they retain spare A class aprons when I would imagine the B2 aprons would be identical? Likewise with them not fitting dual headlights to the As unlike the B2s (the only A to have them was 296, although this may no longer be the case with LED headlights being retrofitted to the tram fleet).

Back in the 1980s Z1 67 (which was the test tram of the day) had a custom apron with a flat front (no oval) and modern lights fitted (identical to those on prototype W8 922). 67 was also the first Z to be fitted with a pantograph and a dot-matrix desto, I believe the desto was also fitted before the B2s came out with their own versions in 1988 (which, along with the same aircon units, were also used in the Met's latest MAN buses). Z3 173 also received a similar desto, unless this was the same unit out of 67 when they standardised on the Z1 destos in the 90s.

Do the high beam on LED lights actually work?  Last time the driver was kind enough to try it for me and it made no difference.
