0-4-2 TANK ENGINES

STURROCK

No. 241 CLASS

5ft-6in wheels, cyls 16½in x 22in

Nos. 241-50 were purchased from Avonside in 1865.

STIRLING
 REBUILDS OF STURROCK ENGINES

No. 12 CLASS

5ft-6in wheels cyls 16in x 24in

General Plan dwg Q25 (9/1871)

The date of rebuilding is not known, but was presumably around 1871.

It was withdrawn early 1893.

No. 43 CLASS
WORKS LIST L

5ft-6in wheels, cyls 16in x 24in

General Plan dwg Q27 (51872) (Bird did not find this dwg, although the LDO had a copy)
Screw Reversing Gear dwg K27 (13/11/1872)

Sturrock Nos. 43, 10,  20, 42 were rebuilt in 1873-74.

 No satisfactory explanation has been found for these engines being given Works Nos. 101/03/39/42.

The boiler barrel was 4ft-0in diameter and 9ft-4½in long. The firebox casing 4ft-5in long and 3ft-11½in wide.

The approximate withdrawal dates were:  Nos. 42 (late 1890),  20 (late 1891), 10 (early 1892), 43 (late 1896).

STIRLING

No. 270 CLASS

5ft-6in wheels, cyls 16in x 22in

Nos. 270-79 were purchased in 1867, five engines each from Neilson and Avonside.

The basic details were similar to those of the 241 Class.  Further engines had been ordered (allocated Nos. 280-94) but Stirling managed to have them cancelled. Stirling rebuilt these engines later.

No. 241 CLASS Rebuilt
No. 270 CLASS Rebuilt
IVATT CLASS F5

Around 1879-81 the engines were given 4ft-5in diameter straightback boilers to drawing N40 (issued 21/1/1879). 

Whilst some of records suggest 241-50 received smaller boilers, the drawing register is clear.  The entry in the drawing register reads "Nos. 241 to 250, 270 to ---" (remainder of line is torn).  The engines were not reboilered again.  Nos. 241-50 were transferred to the Duplicate List (1879-80) which seems hardly the action appropriate if the engines had been given larger boilers.  Four of the later engines (Nos. 270/75/78/79) were transferred to the Duplicate List (1901-04) to make way for new Ivatt large Atlantics.  The engines were withdrawn from traffic between 1898 and 1905.  After they were withdrawn two engines became Departmental engines: No. 241A became LOCO B (12/899-5/1902) and No. 244A became COLWICK LOCO PILOT (12/1899-5/1906).

No. 126 CLASS
WORKS LIST D
IVATT CLASS F4

5ft-1in wheels, cyls 17½in x 24in

Smokebox dwg I27 (13/1/1868)
Frame dwg O8 (4/1868)
Boiler dwg N2 (11/5/1868)
General Plan dwg Q20 (9/1868)

Boiler dwg N50 (18/3/1884) 4ft-2½in diameter "for Repairs to Metropolitan Tanks 131 &c"

Nos. 116-19/21-23/25-27/29/31/32 were built (1868-71) though not in that order.

They had 4ft-0½in diameter boilers, barrel length 10ft, firebox casing 4ft-10in length.  They were given 4ft-2½in diameter boilers (1884-89), the first one being No. 132 (6/1884).

No. 126 CLASS - REBOILERED BY IVATT
IVATT CLASS F6

5ft-1in wheels, cyls 17in x 24in

Boiler dwg N85 (3/1898) 4ft-5in diameter domed boiler, barrel 10ft-1in length, firebox casing 4ft-10in length.

Five engines, Nos. 116-18/22/32, were given 4ft-5in. diameter boilers, 10ft-1in barrel length and 4ft-10in. firebox casing length (1899-1907),  The engines were withdrawn (1905-18).  No. 126A was on the Departmental List (1906-1911) as LOCO H.

No. 501 CLASS
WORKS LIST N
IVATT CLAS F7

5ft-1in wheels, cyls 16in x 22in

General Plan dwg Q40 (2/1876)
Cylinders Pattern 20 dwg M43 (10/2/1876)
Frames dwg O19 (3/1876)
Valve Gear details dwg K35 (9/3/1876)

Nos. 501-03, 161 were built in 1876-77.

They ostensibly replaced three former Stamford & Essendine Railway engines.  The boiler was 4ft-0½in diameter, barrel length 9ft-3in, firebox casing length 4ft-6in.  All four were fitted with the simple vacuum brake system in 1881.  The engines were reboilered: Nos. 501 (11/1892), 502 (12/1892), 503 (3/1893), 161 (3/1893), all believed to be 4ft-0½in diameter.

No. 161 was withdrawn first (September 1907) and Nos. 501-03 were scrapped in 1913.

631 SERIES
WORKS LIST N2
IVATT CLAS F7

5ft-1in wheels, cyls 16in x 22in

No. 631/32 were built in 1878.

These engines were virtually identical to the earlier List N locomotives, with (apparently) minor differences to the cab.  No. 631 was fitted with the simple vacuum brake system in 1882, then Nos.631/32 were both fitted with the automatic vacuum brake system in 1887/88.  No. 631 was withdrawn first (February 1904) still with its original 1878 boiler.

No. 632 received a new straightback boiler (5/1897) to the same original 1876 design (M43, see No. 501 Class above).  This boiler was part of Boiler Order 501 (undated) which could have been a resurrected Stirling order.  No. 632 was withdrawn November 1918.
