Again, that's just why they shouldn't be used. I'll explain the difference:
Shouldn't be used - they are usable, but have features that do not meet current standards
Can't be used - if there's something that actually prevents them from running. I believe that's why MrToastyy made his comment in the first place.
"...because they're a thousand years old..."
I do NOT like this exaggeration, especially when W class trams are still running on routes 30, as well as 78/79 (until Friday). If age really was an issue, they'd only be allowed on the City Circle. Mind you, 845 had its 75th birthday on the 13th of July, and it's one of the green route 30 Ws, compare that to our 42 year old Hitachis
They were actually more comfortable, in my opinion, than other trains (especially compared to X'traps, quite embarrassingly)
"I really wish that gunzels would seperate rational thought from mindless dribble."
And I really wish you would not make such comments, as it is an insulting thing to say, as well as a generalisation that all gunzels post rubbish, which is not true. Since I am a person who really loves Hitachis (and I mean REALLY loves Hitachis), you should consider yourself lucky I even said there's any reason why they "shouldn't be used"
Disclaimer: this post is not to suggest that the Hitachis return to service, it is just to clarify my point.
This is the problem with Victoria and its Public Transport. Just as one would not run a 1980's car for their daily commute, a modern public transport system should not have 42 year old trains which are unfit for Modern Transportation or for that matter 75 year old trams. Age is not an issue in Victoria because the State Government will not spend the money on new stock (Look at the E Class Tram Introduction, 6 Trams in 5 years!!) Modern Transit systems should have modern rolling stock and that means spending money on new stock and not $2 million on W Class Trams, to my mind that is criminal, especially given the state of the majority of the Tram Stock.
Sydney are getting rid of their non air conditioned stock, London are getting rid of their C Stock, because they do not meet modern standards. Get rid of the Hitachis. If they are to be used again, completely gut them and convert them to Modern Non Motored coaching stock for the Warrnambool and Albury Lines.
