What is Block Train?
A block train is a freight train made up of wagons carrying cargo for one consignor that runs from a single point of loading to a single point of unloading without being split or remarshalled en route. The European Commission's study on rail freight defines full trainload traffic in exactly these terms, as several wagonloads transported together with no change in train composition. It contrasts with single wagonload, where individual wagons or groups of wagons are collected and sorted through marshalling yards and combined with other customers' wagons. Block trains can be dedicated to bulk commodities, to a single customer's flows, or to intermodal units such as containers and swap bodies on a fixed shuttle between terminals. The term is also used for container trains on Eurasian routes, where the whole train is booked for an origin and destination pair.
Why it matters for forwarders
Because they skip intermediate shunting, block trains are generally faster and more predictable than single wagonload and are priced per train or per slot on a train rather than per wagon. The trade-off is volume commitment: someone must fill the train, so forwarders either consolidate enough cargo themselves or buy slots from an operator that runs a scheduled block train. On cross-border routes the documentation must suit every legal regime crossed, for example a CIM consignment note in COTIF countries or a combined CIM/SMGS note where the route enters the SMGS area, together with customs transit documents. Gauge changes, border handling and train length limits can still cause delays even when no shunting occurs. Check the operator's cut-off times at the loading terminal, since missing the train usually means waiting for the next scheduled departure rather than a short delay.
