Last time I arrived by train in Wien Hauptbahnhof with 3 airplane checked baggage sized bags (23 kg each), transferred to a local train to Vienna Airport (Flughafen Wien) train station, and there was a big problem: there where no trolleys at the train platform for luggage, and there was quite a large distance to walk from the train station to the terminal.
I thought an airport train station of a major European airport in a very developed country would have luggage trolleys at the platforms, but no, at least I didn't find them. And the train station wasn't even connected with the airport, had to walk outside quite a distance, at least 100 meters.
If I had 4 bags to check-in this would have been impossible. I can hardly believe I am the only person wanting to transfer from Vienna Airport train station to the airport with more luggage then I can carry. Even if they had wheels (not all of the bags have wheels), I have only 2 hands to pull bags, putting 2 of them on top of the other two and trying to roll on the wheels of the lower 2 bags has only a small chance of working without breaking the bag's wheels and the whole thing becoming un-steerable, because of the weight.
What are my options if I were to make this transfer next time with four bags?
