How many fit in a train
The binding limit is usually the shortest passing loop on the route, not the locomotive.
- European norm
- 35 wagons
- 550 m train · 2310 t payload
- TEN-T corridor
- 47 wagons
- 740 m train · 3102 t payload
- Extended
- 53 wagons
- 835 m train · 3498 t payload
Worked example.1320 t needs 20 × Zans, only 57% of a 550 m train (35 wagons). A block train at this volume means paying to haul empty space — the path and the locomotive cost the same whether the train is full or not. Wagonload consolidates your wagons with other traffic, at a higher per-tonne rate but no volume commitment, and adds 1–4 days of marshalling dwell.
Loading gauge clearance
No deck height is published for this type, so clearance cannot be computed. For a tank the governing constraint is usually the discharge arrangement rather than height.
