How many fit in a train
The binding limit is usually the shortest passing loop on the route, not the locomotive.
- European norm
- 26 wagons
- 550 m train · 1040 t payload
- TEN-T corridor
- 35 wagons
- 740 m train · 1400 t payload
- Extended
- 39 wagons
- 835 m train · 1560 t payload
Worked example.800 t needs 20 × Ias, which is 77% of a 550 m train (26 wagons). That is enough to justify running a block train: it goes origin to destination without being marshalled, so it avoids the 1–4 days of yard dwell wagonload adds, and the per-tonne rate is lower because the path and traction are spread over a full train.
Loading gauge clearance
Whether a load clears the tunnels and bridges, on this wagon's 1180 mm deck. This is not track gauge — see the track gauge checker for whether the wheels can run on a given network.
