CHOOSING RAILWAY VEHICLES FOR CARRYING PASSENGERS [PDF]
TRANSPORT, 2010 To carry passengers, diesel and electrical trains, railcars, passenger carriages and hauled locomotives are used in AB ‘Lietuvos geležinkeliai’ (Lithuanian Railways). In certain sections, the number of passengers is very low (e.g. several or up to twenty passengers per 24 hours), and therefore rolling stock is used inefficiently. For this reason, it is
