Questions that you've always been too embarrassed to ask

Could you imagine fitting a 'Differential' to the axle of every rail vehicle to allow the wheels to turn at different ratios on a curve?
The weight and structure alone plus its something else to wear out and break down to make it hideously expensive to use.
The 'Differential' effect is achieved by angling both the head of the rail and the wheel face and of course wide curves.

Some years ago a Dutch company call DAF made a small vehicle that used 2 cones and belts to achieve a clutchless almost infinite number of 'Gears' as well as allowing each wheel to rotate at its on speed on a curve.
This system is still used on Ride On 'yard' tractors used for large area lawn mowing today.

BTW, in the DAF Company museum in Holland is a small van that was driven from Cape Town in South Africa to Amsterdam using this drive method.

And now for something completely different . . .

When the line to Ballarat via Bacchus Marsh was built, it was the start of the main line to Adelaide, and was single line.
The Bendigo line which, by comparison went nowhere, was double line.

Was not the original route to Adelaide via Geelong C, Meredith and Ballarat?
I thought that the route via the Marsh started out as two dead end branchlines that were eventually joined.
Open to correction, however.
