I thought you were a fan of distributed power production...

How about transmission losses, by the way? And autonomy? And avoiding buying power at the marginal price, and having the possibility of feeding into the grid? Also, having the windmills spaced 2.5Km apart all along the line means the intermittency is largely averaged out.

Are there not practical advantages to such a scheme?

I'm still thinking there should be a windmill at the centre of every roundabout. And don't tell me it's ugly: in the US midwest people don't complain about their town's water towers.

Where have I contradicted that?

Maybe along the Transsiberian. For any railway within the EU, the distances are too small, thus intermittance will be a factor; though fortunately, it is just railways that have a quite large share of hydropower. Balancing across the entire railway network of the EU has no plus compared to balancing with the rest of the grid.

The advantage of putting turbines along the railway may be that they could be erected on railway right-of-way, sparing land purchase costs.

We say "let's put windmills along railway tracks" and you say "it's more practical to build large wind farms".

In any case, the factor of at least 6 in energy consumption per passenger-km between planes and trains boggles the mind.

Windmills along railway lines is one large wind farm - and one along a line long enough for weather differences to balance each other is larger than any in existence. On my part I haven't specified the size of the wind farms. And anyway, distributed production and minigrids are two different things not necessarily bound to each other..

To recapitulate: because you have to consider territories affected in a half kilometre radius anyway, and because the site of the best wind is not necessarily along the railway, and because you have long transmission distances along the railway line anyway, railway-feeding wind farms might as well be built as normal wind farms somewhere near the line. Railways might opt to build wind farms, and use as much electricity as their wind farms produce, thus not having to spend on buying net electricity elsewhere, but that net zero would cover having to get electricity from the grid and sending surplus to the grid depending on intermittance. It's best if what they buy is regenerative energy too, and it's best anyway if non-rail users have regenerative sources too, so why not cut it short and create a wind-et-al-fed grid which feeds rail too.
