Classes and Types of Locomotives
Content: They are today very rarely in use. Fuel cell-electric locomotive (hydrail) is very recent type of locomotive. It is powered by hydrogen and it converts chemical energy of hydrogen to  mechanical energy. The first one was demonstrated in 2002 in Val-d'Or, Quebec. Few places have this type of railway like Kaohsiung, Taiwan and some also  have Rail Power GG20B locomotives that work originally on diesel but are converted to hydrogen. Atomic-Electric locomotive was an idea in 1950s when we didn't understand dangers of atomic power too well. It would have 200 ton reactor chamber which  would be coated with 1.5 m of lead.
