Below I give specifics about the French, Italian and Spanish Motorail services. Similar services are offered in most countries. Few sources outside Europe know much about Motorail. To get more info or to make reservations, first visit the website of the rail company you are interested in using. Vehicles are generally loaded two hours before departure of the train, but double check this upon booking.
Free parking is usually available one day before departure and one day after arrival.
In most stations a free car wash voucher is given to Motorail clients. In some cases the loading and collection of vehicles take place in the same station as that in which passengers board and leave the train. When this is not the case a free bus service is usually provided to transfer passengers between the two stations. Note that the size of your vehicle may limit your ability to use the trains. Bicycles must be transported inside your vehicle.
