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It was withdrawn early 1893.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.

Fig. 28 Neilson engine No. 270 |
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).

Fig. 56 No. 246A |
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 The engines were withdrawn from traffic between 1898 and 1905. After they were withdrawn two engines became Departmental engines: No. 241A became LOCO B (12/899-5/1902) and No. 244A became COLWICK LOCO PILOT (12/1899-5/1906).

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.

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.
![]() |
Fig. 69 No. 631 |
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.
