Quite true, it can take ambulances...and buses. But if the major advantage (taking buses) can't be used, the cost of open ballast would have been far less, making it much more economic. This economic issue is what can kill a project. If a government that isn't interested in trams can point to poor economics, it has a very legitimate reason to scrap extension plans. The present government has said it will only do the North Adelaide tram extension if it stacks up economically. Making it needelessly expensive is a death sentence.1NEEDS2POST wrote: ↑Tue Aug 14, 2018 9:32 pmOne unintentional benefit of the track on Port Road and North Terrace is that it can be used by ambulances to and from the RAH. Can't do that with open ballasted track.
The points could be set straight for trams to continue beyond the Botanic Gardens stop. Why would the whole terminus have to be dug up?rubberman wrote: ↑Tue Aug 14, 2018 3:00 pmI agree on the need to consider the long term vision. However, building scissors crossovers with heavy signalling is something authorities do only if that particular terminus is going to be there for a very very very long time. If there was any real intention to extend in the near future, there would have been a simple arrangement like at the Glenelg terminus. Just think, if there was a serious intention to complete a city loop, that whole terminus at the East End would need to be dug up. Either that, or again, it was another example of gold plating.
As for digging the crossing up, well, if it's left there doing nothing, it's a big waste of money. The crossings and point motors and signals aren't cheap. That means that instead of recycling them for some other extension, new expensive ones will have to be bought. So, either they are left in the ground, and wasted through no use, or they are dug up to save money by reusing on an extension. Point is, why spend all that money if you were only going to use them for a couple of years? Nope, they put them in because they thought that was going to be the terminus for a very very long time. That is, they had no intention of extension of the city loop for many years. Same with North Adelaide. At $200m plus, does anyone think it will come out economic?
