Glossary Results for prefix "ga"

‘G’ 0-8-0 Locomotive Class	Mr Whale converted ‘B’ class four-cylinder compounds into ‘G’ class two-cylinder simple engines, retaining the ‘B’ class’s inside frame low-pressure cylinders. As these cylinders were 1in larger in diameter he reduced the boiler pressure to 160 psi so the tractive effort would be about the same. The distinctively shaped covers below the smoke box were retained even though they had nothing to cover. These covers lead to the nickname ‘piano front Gs’.
‘G1’ 0-8-0 Locomotive Class	Super heated 0-8-0, some built new, but 279 rebuilt from classes ‘A’ to ‘G’. The main external difference compared with a ‘G’ class is the longer smoke box, to accommodate the super heater header, though the barrel length of both boilers was the same at 14ft 10in; internally inside-admission piston valves replaced the ‘G’ class slide valves, though the cylinders were the same size. They were originally fitted with super heater dampers, they were soon found to be unnecessary and so removed. At some stage, possibly after first World War, steam heating was added also, not so much for passenger trains, as for working banana specials from Garston Docks. Some 25 specials might be run at short notice when Fyffe’s steamer came in.
‘G2’ 0-8-0 Locomotive Class	In 1921-2 sixty class ‘G2’ 0-8-0s were built. They were a development of the ‘G1’ class with higher boiler pressure, 175 psi (compared with 160 psi). The ‘G2s’ were the only LNWR 0-8-0s which were never rebuilt to some other class, and none were ever painted in lined livery.
‘G2A’ 0-8-0 Locomotive Class	October 1935 ‘G1’ class converted like ‘G2’ class, with higher boiler pressure, stronger motion and increased brake power.
Ganger	A man in charge of track maintenance gang, chargehand.
Gangway	Flexible connection between vehicles to enable train crew and passengers to pass from one carriage or NPCS to the next whilst the train is in motion. Gangways were not intended to permit passengers to promenade the train and the gangway doors were normally kept locked except to allow them access to the dining car. Gangways were normally central in the end of the vehicle though TPOs and certain vehicles intended to run with them had Lansdowne pattern side gangways which increased the available working or stowage space. Central gangways were of the “British Standard” type which enabled carriages of different companies to run togther.
Garratt Pick-Up	The apparatus consisting of the traductor arms and receiving nets located at the line side and on the vehicles by means of which mail bags were picked up and set down (often simultaneously) by Travelling Post Office carriages at speed. The patent of a Mr Garratt (a Post Office employee).
Garstang & Knott End Railway (GKER)	The GKER ran from Garstang, on the LNWR main line north of Preston, to Knott End, opposite Fleetwood on the other side of the River Wyre; it was not part of the LNWR.
Gas-oil Tank	A storage tank which contained gas oil (i.e. naptha, or oil which was converted into gas as an illuminant in carriages). Today gas oil is another name for diesel fuel oil.
Gauge	The distance between a pair of running rails, measured from inside edge to inside edge. See also Broad Gauge, Mixed Gauge, Narrow Gauge and Standard Gauge. Also Model Gauge
Gauntletted Track	Where rails of parallel tracks are arranged so that the inner rail of one set is between the rails of theother. Normally adopted to allow additional working space on a viaduct or in a tunnel under lengthy repair. Effectively reduces the section concerned to single track without the expense of installing full points, but must be signalled accordingly. Also known as interlaced track or interlacing.
George the Fifth 4-4-0 Locomotive Class	A class of 4-4-0 locomotives built by Bowen Cooke from 1910, a superheated development of Whale’s “Precursor” class, and named after the first of the class. Initially “Queen Mary” (the second in the class), was built without superheating, for comparative trials with its sibling. Following the trials later members of the class were built superheated and “Queen Mary” was also converted. Engines of the class probably performed more prodigious feats of hauling heavy trains at high speeds than any other 4-4-0.
Gig	A light two-wheeled road carriage pulled by one horse.
Glasgow & South Western Railway	Not part of the LNWR - a railway company whose lines were confined to the south west of Scotland and whose main line ran from Carlisle to Glasgow via Dumfries. When the Midland Railway reached Carlisle on completion of the Settle and Carlisle line, its trains continued to Glasgow by the GSWR.
Glass Wagon	A specialiased wagon to carry plate glass.
