Gradients in Victoria

 
  Duncs Chief Commissioner

Just a general question. What are the gradients for the steeper climbs for trains in Victoria?

I am asking with regard to;

Islington bank - on the down Baccus Marsh to Ballan
Craigeburn to Heathcote Junction (or should that be Kilmore?) on the down to Seymour
Sunbury to Kyneton on the down to Bendigo

I am guessing it is around 1 in 40, but that is just a guess.

One of the Steepest climbs in Victoria on the BG network is the 1 in 30 between Upper Ferntree Gully and Upwey.

On closed lines there was plenty of 1 in 30 between Everton and Yackandandah. While there was plenty of steep grades, on the Cudgewa line, there was only a little bit of 1 in 30, most grades were between 1 in 34 and 1 in 40.

Really. all you have to remember is:
  • 1 in 50 on main lines.                          (Except for 1 in 48 to Seymour and Ballarat.)
  • 1 in 40 on important branch lines.    (And most minor branches.)
  • 1 in 30 on a few hilly branch lines.    (Beechworth, Cudgewa and on the narrow gauge.)

Did Vic Rail use a form of 'Grade Control' similar to NSW that controlled the exhaust of the Air during a brake release ?

I know on the Oberon Branch, UP Trains had the Hand brakes 'wound on' to assist in the descent to Tarana and between Katoomba and Valley Heights, there was provision in the rules for a Train under 750 tons to run with the Hand Brakes applied instead of using the Grade Controls.

Thanks Bogong

I have seen a You Tube video of a type 68 Vossloh loco in the UK pulling 8 carriages very easily up a 1 in 37 gradient. Which prompted me to start this thread. So I don't think it will have too many problems operating here. I covered this locomotive in an earlier thread as a likely replacement for the N Class, so no need to re visit that topic. But in another You Tube video I timed the Type 68 with seven carriages, reaching 120 kph from a standing start in 90 seconds.

Food for thought.

No, neither the terrain nor the trains to need to.
