Class Details by Steve Llanso of Sweat House Media
Class Lintz (Locobase 8183)
Data from Colin E Mountford & LG Charlton,"Lintz" (Industrial Railway Record #15 (September 1967), pp 95-99, archived on [
] (last accessed 9 February 2007). Works number was 258 in 1873.
The Lintz Green Colliery itself (near Consett in County Durham) opened up in 1855 and its pits were served by stationary engines. In 1871, George Henry Gooch took control. Among his actions was to open subsidiary "drifts". The West Lintz or Brass Thill Drift was served by a 2'-gauge railway whose first motive power example was this tiny saddle tank. A coke- (rather than coal-) burner, the Lintz had a self-centering radial axle that used a heart-shaped cam to keep it in line.Both its rail gauge and its wheel arrangement appeared rarely in Black, Hawthorn's production list.
The 2-mile(3.2 km) line's profile was not for the timid. Half the distance rose at a 2% rate while much of the rest featured adverse gradients (i.e. the direction in which a loaded train traveled) of 1 in 65 (1.5%), 1 in 82 & 1 in 84 (about 1.2%). An average train consisted of 20 full wagons weighing a total of 22 1/2 long tons (25.2 short tons).
The great depression of the middle 1870s led to the closure ("laying in") of the West Lintz Drift in 1878 and the idling of the Lintz and an 0-4-0ST. It's not clear what happened to the Lintz. It may have ended its days as a stationary boiler.
