 4rail.net - Reference - Rolling stock - JT42CWR / Class66        

Class66 is one of the most successfull diesel locomotive types in Europe. The locomotive is based on the proven American robust locomotive (roughly an SD70 construction) adapted to European requirements. Hundreds of this type earn income to their owners every day year round. A successor class 67 has a number of things further improves, among these one that is strikingly poor for the class 66: the crew conditions.
   
The JT42CWS/JT42CWSM/class66 has become a symbol to diesel success in Europe, as many of the open access operators operate the type. The diesel locomotive can operate independently of dozens of European electric companies and 4 main electricity distribution form standards. As long as the 1435 mm (4' 8,5") gauge applies, which is most of the Western Europe. 
     
Amazingly, in just 10 years this locomotive has been taken into use in at least 13 European nations for tens of operators! As an American design made to cross the mountains, to be used almost continuously and survive with minimal maintenance this locomotive is at home both in the rough winter conditions in Nordic countries and in summers heat in southern France.

 Why the class 66 is popular
What is special about class 66?
The class 66 has become immensely popular among the operators. We can pinpoint at least 3 reasons for this success:
  1. Interoperability in Europe. JT42CWR is certified for large majority of the European Union countries and countries around them. A few member countries had chosen not to certify the locomotive, which will lead to interesting situations, once the rule that if a rolling stcck is certified in one member country, it should be allowed to operate in all others (some restrictions like train control systems still apply) comes into effect.  
  2. Critical volume. Once the locomotive is common enough that dozens of operators own it, you are almost guaranteed to have the aftersale market, be able to lease and lend locomotives, and be able to acquire services and repairs easily.  
  3. Successfull design. Although the crews have reported about the poor spartan cabin, the locomotive is otherwise very durable and made to last. The capacity is just high enough to pull a medium sized freight train (for Europe) and while the loading gauge is "obsolete" (the smallest in Europe, that is the British loading gauge), the size that way is not the issue anywhere.
