Freight trains can be found in most European Countries and often carry rideable cars. Auto Racks (automobile carriers), Boxcars, Coil Cars, Flat Cars, Grainers, Gondolas, Tanker Cars, and Well Cars can all be found. Most are electric, traveling far and fast. Which is fortunate since very long tunnels are found in Europe, and diesel trains going through tunnels require a 'skank' or piece of material which you must dampen and tie around your mouth and nose to avoid asphyxiation. Big part of European railways are electrified. Don't go climbing up on the roofs of railway cars, even when they don't have visible power racks or railroad you're traveling is not electrified. Railroad might have wires on later parts. There's very high risk of getting electric shock on roof of a car.

Conductors, controllers and engineers or rail workers have no concept of 'hoboing' in Europe, so be prepared to have a good explanation if you get caught. All yard workers wear bright vests, so you can see them from a distance, however this also means a moving body without a vest is likely to raise attention. Keep low, stay safe. 'Bulls' or railroad police don't exist (I don't agree with this, for example in Slovakia they do exist. ) on many countries in Europe so you're off the hook there. Guards around stations can be found.
