‘G’ 0-8-0 Locomotive Class
Mr WhaleExplain 'Whale, George (1842—1910)' converted ‘B’ classExplain '‘B’ Class 0-8-0 Locomotive class' four-cylinder compoundsExplain 'Four Cylinder Compound' 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 psiExplain 'PSI (Pounds per Square Inch)' 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’. View more details
‘G1’ 0-8-0 Locomotive Class
Super heatedExplain 'Super Heated Steam' 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 boxExplain 'Smoke Box', to accommodate the super heater headerExplain 'Super Heater Header', though the barrel length of both boilersExplain 'Boiler' was the same at 14ft 10in; internally inside-admissionExplain 'Inside Admission Valve' piston valves replaced the ‘G’ class slide valvesExplain 'Slide Valve', though the cylinders were the same size. They were originally fitted with super heater dampersExplain 'Super Heater Dampers', they were soon found to be unnecessary and so removed. At some stage, possibly after first World War, steam heatingExplain '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. View more details
‘G2’ 0-8-0 Locomotive Class
In 1921-2 sixty class ‘G2’ 0-8-0s were built. They were a development of the ‘G1’ classExplain '‘G1’ 0-8-0 Locomotive Class' with higher boiler pressure, 175 psiExplain 'PSI (Pounds per Square Inch)' (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. View more details
‘G2A’ 0-8-0 Locomotive Class
October 1935 ‘G1’ classExplain '‘G1’ 0-8-0 Locomotive Class' converted like ‘G2’ classExplain '‘G2’ 0-8-0 Locomotive Class', with higher boiler pressure, stronger motion and increased brake power. View more details
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 NPCSExplain 'Non-Passenger Coaching Stock (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 carExplain 'Dining Car'. Gangways were normally central in the end of the vehicle though TPOsExplain 'TPO – Travelling Post Office' and certain vehicles intended to run with them had LansdowneExplain 'Lansdowne side gangways' pattern side gangwaysExplain 'Side Gangway' 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 armsExplain 'Traductor Arms' and receiving nets located at the line sideExplain '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 GaugeExplain 'Broad Gauge', Mixed GaugeExplain 'Mixed gauge', Narrow GaugeExplain 'Narrow Gauge' and Standard GaugeExplain 'Standard Gauge'. Also Model GaugeExplain 'Model Gauges'
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 viaductExplain 'Viaduct' or in a tunnelExplain 'Tunnel' under lengthy repair. Effectively reduces the section concerned to single track without the expense of installing full pointsExplain '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 CookeExplain 'Bowen Cooke, Charles J (1859—1920)' from 1910, a superheatedExplain 'Super Heated Steam' development of Whale’sExplain 'Whale, George (1842—1910)' “Precursor” classExplain 'Precursor 4-4-0 Locomotive Class (2)', 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 RailwayExplain 'Midland Railway (MR)' reached CarlisleExplain '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.
