   Diesel-mechanic transmission  evaluated  
Diesel-electric and diesel-hydromechanic transmission are dominant in modern diesel stock. However technological progress in mechanical transmission has increased interest in diesel-mechanic stock in recent times.
Technology field: Optimisation of traction technologies
close main section General information
  close sub-section Description
   

In the second half of the 20th century diesel-electric and diesel-hydraulic stock has widely replaced older diesel stock with mechanical transmission. With advances in gear technology, some manufacturers and operators are recently starting to rediscover diesel-mechanic propulsion for reasons such as low price, low weight and high efficiency.

Manufacturer

  • Ansaldo Breda (IC4 for DSB)
  • Siemens (Desiro)
  • Bombardier (Talent)
  • etc.
