Arefuge siding is a single-ended, or dead-end,siding off a running line,[1] which may be used to temporarily accommodate atrain so that another one can pass it. For example, a refuge siding might be used by a slowgoods train to allow a fastpassenger train to pass.[2] It is similar in concept to apassing loop but is connected to themain line at only one end, rather than both ends.
On the Japanese railway network, 8 refuge sidings (known locally as a form ofswitchback) remain in day-to-day use –Obasute Station,Hatsukari Station,Nihongi Station,Tsubojiri Station,Shingai Station,Kuwanaohara Signal Box [ja],Takiyama Signal Box [ja] andNakazaike Signal Box [ja] – while 48 former refuge sidings, now converted into conventional passing loops or abandoned, are attested. They are mostly used by stopping passenger trains and freight trains, especially in cases where express trains are scheduled to pass.
Sometimes refuge sidings were needed where there were steep ramps on the line. For example, atGresford railway station inNew South Wales, the gradient was so steep that a refuge siding was required at the station in case some of the wagons or coaches of a train had to be left behind so that it could climb the hill.
In British and Australian practice at least, it was common to refer to such sidings as an "Up refuge siding" or "Down refuge siding" depending on the orientation of the siding in relation to the direction of travel.
