No, however some trains have a magnetized wheel to help grip the track.
*Added -
Electric trains do result in short term magnetizing of the train tracks. This can be seen on sharp curves where tiny rail slivers cling along in a magnetic pattern. In the US, trains do not have magnetized wheels, but rapid trainsit systems can include a track brake that uses a magnet to provide much faster braking than the wheels alone.

Do bullet trains have wheels?
Yes, bullet trains have wheels. They run on rails, just as conventional railroad locomotives and cars do. The trains that operate by magnetic levitation, the so-called MagLev trains, do not have wheels as they ride on a magnetic cushion.
Why do railway tracks have gaps in them?
Railway tracks have gaps to allow for expansion when the tracks heat up. As the tracks get hotter, they expand and get slightly larger. Without the gaps, the tracks would buckle from the force of the expansion. They have fishplates located between the joins to force the rails back into lateral alignment and thus prevent derailments.In modern continuously welded rail these gaps are often cut on a diagonal to prevent this misalignment. The thermal expansion and contraction of rail track is minimal and the forces push to the outside rather than along the rail.They are also there because segments of rail have traditionally been required to be removed and replaced easily and so had to be made a manageable length.Heat expands metal, to prevent buckling in the rails the tracks are in pieces with gaps. Another reason is in case of lighting strike the electric current can only travel as far as the first gap, this preventing electrical charge getting to a train car or electrical box.because the railway lines expand during the summer and by the friction of the train with it . if the gap is not kept the rail lines would expand and break. so to avoid the breaking of the rails the gap is keptThere is gaps between railways because during summer when the sun will heat the rail which is made of iron will obviously expand.After some calculation an approximate distance is left between them.After this answer you will ask but what in winter and how does the train pass on the gaps?So this gap is nothing for the train. It is left so that during expansion when the railways will expand the rail will not change direction.For e.g:-imagine when you take 2 drinking pipe and joint them together it will change direction or even damage.when heat is supplied to a substance or material it will expand.during summer the tracks get heated as a result it will expand. if gaps are not provided, that may result in the bending of tracks.Railway tracks have expansion joints to prevent them from warping when they expand during very hot weather. The metal on railway tracks can conduct a lot of heat during sunny periods.There are small gaps between the length of the railway track because when the temperature is hot the metal will expand and cause the train to crash. So if there is a gap between the length of the train tracks the metal wont join together and cause the train to crash. When the weather is hot have you ever noticed that the trains go slower? Thats just in case the metal joins together.A.thermal conductivityB.specific heatC.thermal expansionD.thermal insulationThe gaps are there to allow for the expansion (lengthening) of the rails in hot weather. Without any gaps, the rails would buckle and go out of alignment.
Is it possible for a train to run without train tracks?
Classic train tracks (two beams each side) can be removed in favour of a Maglev style track (one bar running through the middle). But essentially no due to the driver having no steering control
How many cylinders in train?
It depends on the type of train. A steam powered train only needs on cylinder. Modern trains are actually run by electric motors! The motors are powered by powerful diesel engines that generate electricity as the motors need it.
What are the advantages to the maglev train?
MagLev (or magnetic levitation) trains have no moving parts and therefore need much less maintenance and are nearly silent. They run on superconducting magnets and don't require all of the fuel that current trains do and reduce the amount of carbon dioxide released into the atmosphere. The superconducting magnets are run alongside each other. This would mean that for the train to stop running both magnets would have to fail in the time it would take the train to reach the next stopping point which is only a few minutes. The probability of this happening would be less than once in millions of years of operation.And I like the way it looks!!!!!!!!! The electromagnets that are used in the train are easily turned of so there will be hardly and chance of missing your stop. They also go 359mph. Three times the speed of an average car.it also has less friction henrymeadstinks.
What railroad trains run on?
Trains run on tracks. The tracks are made up of a pair of parallel rails.
Why should anyone not play on the railway tracks?
Because if you don't notice the trains approaching you can get run over, which probably is quite unpleasant.
What is rail transportation?
Trains that run on tracks.
Will the thomas trackmaster trains run on the wood tracks?
Yes
What does the trans Siberian railroad mean?
It is the railway line (and trains that run on it) that crosses Siberia.
Which of the express trains run by Indian railways?
There are about more than 2500 express trains run by Indian railway, check out the complete list @ http://www.indianrail.gov.in/mail_express_trn_list.htmlTravelKhana
Why are rails on railway track fixed to large wide wooden sleepers?
The width apart of rail tracks are set to the gauge of the trains and carriages that are allowed to run on those tracks. They are kept in position by wooden sleepers, though concrete sleepers are often used nowadays.
Although trains were invented long ago what kept them from being really efficient?
Even though trains had been around awhile, they could not run efficiently on poor quality tracks. Their tracks were too brittle.
Is there a railway in star city Saskatchewan?
Yes trains run across it daily
Where is the Indian railway reservation located?
The Indian railway reservation is located in India and runs throughout the entire country. Visitors can ride the trains that run along the railway for the experience of it.
Can trains run if the tracks are iced?
Yes. Although not an ideal scenario, you can sand the rails and hope for the best.
Where can I find a time table for Railway trains from Toulouse to Carcassonne?
If you look at www.tgv-europe.com you can find out what trains run on what days etc, and you can book tickets too.
