Hi all,

Well now, even Melbourne had some with 21E trucks or similar, however they didn’t have any other round devices rotating on a fixed – also rotating – contrivance situated under some other extended part of the body.

Nice pic that btw.

Did you notice the building behind the tram – that was the former Ferry Office with the jetty just able to be made out on the right.

Hi all,

What is on a tram that makes the weight 60 something tonnes?
Is it air con, inverters and other gadgets?

Have the travelling public gotten so soft that they have to travel with the comforts of home for such a short time span?

Anyhow, getting back to the trams, has any model with a fixed bogie ever been a real success, other than for tearing up rails esp. on curves?

Gday Mal,All

Strewth,the W only had 4.5 ton axle load,about 6 ton full load and with
real swiviling trucks
No wonder the rails get chewed,esp on curves,esp with the rigid trucks

Cheers, Mick
