Double-decked train design is a very attractive option for a variety of application contexts. While double-decked trains have a higher compatibility with infrastructure than wide-body trains, life cycle costs per seta are often in favour of the latter option. Even so, LCC per seat of double-deckers are usually better than in single-decked trains. Energy efficiency effects are very promising. Technological barriers are low and infrastructure problems are usually limited to isolated points of the network. Especially in local and suburban operation, double-decked stock should be used wherever a wide-body design is not feasible. Those operators not using double-decked high-speed trains yet should develop design solutions meeting all comfort and operation requirements together with manufacturers. |
