Re: The narrow gauge question? Best gauge?

Actually the Saxon 75cm gauge lines used Rollwagen rather than Rollböcke.

Rollwagen were transporter trucks on which the standard gauge wagons could
be rolled and clamped into position. There were eight-wheel and
twelve-wheel versions. I do not think they dated from the construction of
the first Saxon 75 cm gauge lines in 1881, but they were in use by early in
the twentieth century.

Rollböcke were individual four-wheel bogies which were clamped under the
axles of standard gauge wagons. 75 cm gauge Rollböcke were used in the
German state of Wuerttemburg, but I think they might be a relatively modern
development.

The type of transfer facilities for Rollböcke were more complex than for
Rollwagen. Rollböcke required a long deep pit under the standard-gauge
vehicles, Rollwagen just needed a simple ramp.

It was possible to carry bogie standard-gauge vehicles on Rollwagen, with
one Rollwagen under each standard gauge bogie, and a long reach-bar linking
the two Rollwagens.

The transporter trucks used on the Leek & Manifold Railway in England used
the same principle as the Rollwagen.

The Harz Mountain Railway was metre-gauge, so they certainly would have
been more stable than the 75 cm gauge Rollböcke and Rollwagen.

Those on the Saxon 750mm gauge lines were equally effective.

The 'Rollbokkers' (the bogies placed under the axles of 4 wheel standard
gauge wagons), used on part of the Harz (East Germany) would have followed
that rule. They appear to be quite stable.
