Quote from: triumph on April 28, 2019, 05:09:33 PMThe LRVs now have module identification underlined, with fleet number below, inside each module. Module identifications are C1 - S1 - R - S2 - C2. This is slightly different from identification used by CAF (Mc-S-T-S-Mc).

Quote from: triumph on December 02, 2021, 11:17:56 PMThe Canberra Times today at page 12 (print version) reports on a thorough examination of LRV11 for cracking and found none. This followed the standing down of the Sydney fleet operating the Central to Dulwich Hill route after the discovery of cracking. The item says that LRV11 is at the time of inspection, the most travelled of the fleet at 192,000km. It also remarks that (being of a slightly newer manufacture) that there are structural differences between the two CAF fleets (even though both are the same basic model).Interestingly, in Sydney's fleet, cracking was found in the 'bump stop'. This implies to me rougher track with consequent stresses on their LRVs which do not apply to Canberra. Most of the Central- Dulwich Hill route uses former heavy rail track disused when freight trains ceased operating. As such with sleeper and ballast it is quite different to the arrangement in Canberra where rails are fixed in a concrete slot with a commercial fixing fill for an inherently smoother life. I recollect riding to Dulwich Hill a while back and wondering at the time what was to be done about track ballast maintenance, as the ride was quite rough here and there.Another interesting detail I came across may provide a reason for the newer fleet used between Circular Quay and Kingsford/Randwick not being available to use to Dulwich Hill. The CAF Dulwich Hill route requires the LRV wheels to suit heavy rail profile, whereas the newer fleet has a profile to suit the newly laid street running track with normal grooved rail. The differences are subtle with no change in the basic gauge. And yes, the newer fleet can move along the Dulwich Hill route, under particular conditions, when needing to go to the heavy maintenance depot, but not for ordinary everyday running.
Quote from: ajw373 on December 08, 2021, 01:36:17 PMBiggest issue running the Alstom trams on the inner west line are floor height difference, in particular the Alstom is slightly lower which means when doors open they can hit the platform. Hence why they can operate out of service on the line. Profile is also an issue but easily solved in the wheel lathe.
