Articulated trains (Jakob-type bogies) |
 |
evaluated |
 |
|
|
| Whereas conventional stock consists of individual carriages resting on two bogies each, articulated trains consist of a fixed composition of coaches with consecutive cars resting on shared bogies. This considerably reduces train weight per length.

Articulated trains are considerably lighter than their conventional counterparts. They have been used successfully for decades in all classes of passenger service. Short units of articulated trains used in local and regional service usually meet no major barriers. Longer units needed in main line and high-speed service often require additional buildings for maintenance and repairs. The corresponding transition costs represent the main barrier for articulated trains. Those operators not prepared for fixed train-sets should first exploit the potential for shorter articulated trains in local and regional transport and reconsider vehicle strategy in long-term. |
