Switchers stalling? Please no.

[Schraddel]

Extreme examples to show what is possible.

Two times the same loco. 2-10-0s of German prototype choosen as examples.
One is unmodified, this is the loco with high flanges and spoked pilot wheels.
The other one is modified in acordance to the 3-point rules, the "old ones" in conclusion with sprung loaded axles.



The extreme roadbed without locos.

The unmodified loco:



Look to the third, fourth and fifth drivers. Even the european practices of high flanges can't avoid derailing. The flanges are above the railhead and so they are no longer capable to guide the loco.

The modified one:



The flanges were turned down to an height of app. 0.25mm.
All wheels are still on the railheads and will stay there whether there are good laid rails or very bad laid rails.

Greetings Lutz


P.S.
ACHTUNG! Warning! German humor!

Question: Is this a loco or a dog?
