* Riding on the outside is a much more exciting (and potentially deadly) way to travel by train than riding inside of it. You can feel the wind and observe your train during it's motion.

* Analyse differents Analyze different parts of train and avoid hanging and grabbing on shaky parts of car (like rusty handles, mirrors, wipers and etc.), which could be breaked broken by weight of a human.* Take the most comfortable and stable posture during the ride. Always have 3 fulcrums while riding on front, back or sides of train car (stand on two legs while holding with one hand, or hold with two hands while standing on one leg and) and maintain weight of your body to different parts of train to avoid falling off it in case of breakage of handle or emergency stop.* Keep the safe distance from electric catenary, currents collectors, busbars and dynamic brake resistors of a train. Note that height of catenary can vary during the ride, ; for example , it's much lower under bridges or inside tunnels. There's very high risk of getting electric shock on roof of a car if you are closer than a half of meter to AC power line or electric equipment of a train: for example, in case of 25 kV power line, an electric arc can occur at a distance of 10 to 45 cm, depending on the weather conditions. If you keep the distance more than one meter from electric currents, you get an acceptable level of safety even if you ride during the rain under an 25 kV AC power line, however, roof riding under a power line is not recommended during a thunderstorm due to high level of air ionization* Watch out for bridges, traffic lights, tunnels, platforms, and other trains if you ride on side or roof of a train and keep the safe distance from them, or immediately get into the loading gauge of train if there are too close. If it's impossible to ride inside a loding loading gauge of train, check the railway lines for close railway infrastructure before rides. For example, the structure gauge in many subways is too close to loading gauge of train, so attempts to ride on it's roof or side can be deadly in case of collision of rider with a tunnel infrastructure.

Big part of European railways are electrified, so be very careful if you want to ride on the roof, especially under AC power lines (riding under a DC power line is much more safe). Don't don't go climbing up on the roofs of electric multiple units (you can do that only if the emplacement of electric current collectors and busbars on the roof allows to keep a safe distance from it during climbing and riding) or on the roofs of high railway cars (such as high boxcars, enclosed auto racks, double-decker passenger cars), even when they don't have visible power racks or railroad you're traveling is not electrified, because railroad might have wires on later parts. In upper parts you'd also be more visible and if people spot you, they might call police.

Russia is a very good place for train hopping. There is an extensive rail-network with a lot of passenger and freight trains, which have a big amount of handles and footrests. Hopping a trains in many regions of Russia is much more common than in most European contries and has it's own history, in . In recent times it became popular among young people aged 14 to 25 years, who live near railway lines.

In a number of Russian regions with a high number of railway lines, especially Moscow, riding on the outside of trains is so common, that some rail workers and engineers of other trains usually don't report about persons travelling on the outside of trains, and civilians never tries to call the police. The railroad police and guards periodically can be found around big and medium train stations and railway terminals, but if they see a rider on the outside of a moving train and can't arrest him, they usually don't report to the next stations, the two only exceptions are subway trains and high-speed trains "Sapsans". In Russia, only the railroad police can arrest you and it never use road cars, so you can stay calm if you see a car of road or civil police. Finally, train hopping in Russia is much less punishable than in the USA or Europe: the fine for that is only 100 Russian roubles, that approximately equals 3.2 USD or 2.5 Euro, that is one of the reasons why the police do not have much interest for train hoppers. However, it doesn't relate to trainsurfing on metro trains where the fine is about 385 USD. In other post-Soviet countries, hopping a trains is less common, and fines much be are higher - for example, in Ukraine or Belarus the maximum fine approximately equals 33 USD.

Trains un in Russia are not so as fast as European trainsones: the an average speed of freight and train is 45-60 km/h. For the most of passenger trains in Russia it is between 60 and 90 km/h with maximum speed of 110 km/h, but some passenger trains can accelerate to 160 km/h. The only high-speed line in Russia is a Moscow - St.Petersburg railway, where express trains have average speed 190 km/h and maximum speed 250 km/h. The big part of Russian railway railways lines are is electrified. There are two electrification types - 3 kV DC and 25 kV AC. The first type of elictrification is common for railways, where the first electric trains was appeared, including Moscow, St. Petersburg and some other regions; while the second one, which is much more dangerous, where the electrification apperead over the last 50 years. The full map of electrification of Russian railways can be found [http://www.gdevagon.ru/scripts/info/map_old.php here]. Be very careful if you want to ride on the roof under a 25 kV power line, especially if train has current busbars between carriages.
