There's a short train ride with just over a mile on one side and just under a mile on the other. (Utrecht, by the way.) Which is perfect for a Boosted Board, were it not that they are expensive enough for me to go over my (arguably low) credit card limit.
So I'll probably bike/bus one part and walk the shorter one, or get another bike. Good asphalt bike lanes are everywhere anyway (...which is perfect board surface material. too. A man can dream...).
