No William, nobody said anything about misusing the linebreakers.

My favour spot for a VERY LOUD opening was taking a W5 up that steep bit of Market St city which is narrow there between the tall buildings.

I would notch up quite rapidly then cut off for the Flinders Lane curve when drawing a high Current. The echo in that narrow location was VERY IMPRESSIVE!

The RC trams were useless.

Their design which IMHO was totally stupid caused the notching fingers to open at the same time as the LineBreaker, thus dividing the current all around with no single point opening under all the load. And of course burning all the little fingers in the process. They didn’t make much of a noise there at all.

The Sydney Standard (Red) Sets also made quite a pop under heavy load. Apparently there used to sometimes be flashovers inside the basically sealed linebreaker enclosing box until somebody decided to see what happened when the box doors were propped open. That apparently solved the problem and the boxes were redesigned with a new front which left the arc chutes open to the air.

I used to love it when a driver coming into Wynyard or Town Hall had the brakes on a bit too hard so to get the train to the end of the platform, applied power. You could hear the gears and motors straining until the brakes stopped the train anyway, then the big POP!

The “snap” of the linebreakers closing, especially whilst drawing high amps was and is frowned upon by those that care on the Comeng trains in Melbourne. I assume the same sentiment was felt on the trams, Richard?

Thanks Matthew. I'd be glad to assist - financially or otherwise! I'm looking forward to being able to hear the SNAP of the line-breaker opening under load if the 'driver' notches up too quickly!

I'm creating a tram-driving simulator. The photo shows the controller type RB-1 in an early stage of construction. It uses an Arduino microcontroller board to communicate with my PC. I'm sure somebody has already done this (e..g. Microsoft Train driving simulator) but I like doing my own thing. (I've been writing programs for 51 years this year!)

What I would like to get is a good recording of the gear noise during notching-up - especially from a spur-gear (as opposed to helical-gear) tram - e..g. a Melbourne W2. I've tried creating the sound with a synthesiser but couldn't get it right.

Any suggestions welcome!

I'll have to try to remember to record 249 at Loftus. I have recording of brake release and the gongs, but I never attempted motor recordings.

Need to ride 249 on a non-traffic day so the motor hatches can be up to get the sound clearly.
