is a flat-bottomed boat
, built mainly for river
transport of heavy goods. Most barges are non-self-propelled and need to be moved by tugboats towing them or towboats
pushing them. Barges contended with the railway
in the early industrial revolution
but were outcompeted due to low speed and falling costs of rail transport
. Barges are still used today, as the cost of hauling goods by barge is very low.
