Re: TAN: Tram and light rail gradients in Sydney.

Gday  Mal, All

According to a dwg liberated from the old Hanna St Depot the steepest
grades in Melb are 1/15,Warragul Rd to Through Rd and somewhere on West
Coburgs,Others will know just where it is

When the Hawthorn Driving School was running,Trainee Drivers has to do a handbrake stop going down from Warragul Rd on the 1/15

The late Robert Aspinall,on his test broke the handbrake cable so
Wilbur Wright,a Driving School instructor said "Righto,you pass"

Trams used were Camberwell W2  This was in the 60s

Calantina Hill in Glenferrie Rd must be close to 1/15

Cheers,    Mick
