Lambton Colliery 0-4-0 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 6325)

Data from chart of locomotives in service on 3 colliery lines on 1 Jan 1948 published on [] (viewed 12 Oct 2004). Locobase estimates a 3" tire in the driver diameter shown in the specifications.

Builder's #1412 was delivered to LH & JC. Although possessing the same power dimensions as the earlier Hawthorn Leslie saddle tanks (see Locobase 6325), the data show a smaller boiler. Locobase wonders about the heating surface, however, as the reduction in tube number is only 6 and the tubes are slightly longer. The firebox was bigger, certainly.


Class 12 (Locobase 6326)

Data from chart of locomotives in service on three colliery lines on 1 January 1948 published on [] (viewed 12 October 2004). Locobase estimates a 3" tire in the driver diameter shown in the specifications.

The first of the this class of saddle tanks was builder's #2789, delivered to LH & JC in 1912. It seems to have represented an attempt to get much more power out of this lilliputian wheel arrangement. See the earlier 32-35, Locobase 6329). 13-14 (3055-3056) followed in 1914.


Class 15 (Locobase 6327)

Data from chart of locomotives in service on 3 colliery lines on 1 Jan 1948 published on [] (viewed 12 Oct 2004). Locobase estimates a 3" tire in the driver diameter shown in the specifications.

The later-renumbered 16 (builder's #96) was actually delivered 5 years before 15 (builder's #169) . These were the first Hudswell Clarke locomotives on this colliery railway, but not the last. In 1881, Hudswell Clarke delivered a nearly identical sister -- LH&JC #22/builder's 230. See Locobase 6328.


Class 22 (Locobase 6328)

Data from chart of locomotives in service on 3 colliery lines on 1 Jan 1948 published on [] (viewed 12 Oct 2004). Locobase estimates a 3" tire in the driver diameter shown in the specifications.

Although nearly identical to the two earlier Hudswell Clarke saddle tankers, this locomotive had a slightly larger grate and a boiler that could pressed a bit harder.


Class 32 (Locobase 6329)

Data from chart of locomotives in service on 3 colliery lines on 1 Jan 1948 published on [] (viewed 12 Oct 2004). Locobase estimates a 3" tire in the driver diameter shown in the specifications.

Hawthorn's delivered the first pair in 1910 (builder's #2826-2827), another in 1912 (2954), and the last in 1913. The 0-4-0STs from the same company that began delivery in 1912 (Locobase 6326) were quite a bit larger.


Class 47 (Locobase 6330)

Data from chart of locomotives in service on three colliery lines on 1 Jan 1948 published on [] (viewed 12 Oct 2004). Locobase estimates a 3" tire in the driver diameter shown in the specifications.

When the LH&JC added to its Hawthorn Leslie stud 10 years after 35 was delivered, they bought two very similar locomotives, but with more and slightly more slender boiler tubes. Total heating surface area increased.
