Scandinavian and Dutch cities no doubt have a far better approach, mind !
Not too sure about that.
In Sweden bicycles are allowed on a few local services but are otherwise banned from all trains.
In Norway bicycles are allowed on most, but not all trains. On some trains a space needs to be booked well in advance.
Bicycles are carried on most trains in Finland, often in special compartments for which a ticket has to be purchased in advance. In the metropolitan area bicycles are not permitted on trains between 07.00 to 09.00 and 15.00 to 18.00
In Netherlands bikes can be carried free on standard service trains during July and August. During the other ten months they can be carried upon purchase of a €6 ticket except during rush hours when they are banned. Bicycles are banned completely on some high speed services. Where they are allowed they have to be dismantled and packed in a cover. Reservation may be necessary and there may be a charge.
