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.

Fig. 48
No. 12

It was withdrawn early 1893.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  The engines were withdrawn from traffic between 1898 and 1905.  After they were withdrawn two engines became Departmental engines: No. 241A became LOCO B (12/899-5/1902) and No. 244A became COLWICK LOCO PILOT (12/1899-5/1906).

No. 126 CLASS

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.

Fig. 42
No. 119

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.

Fig. 68
No. 502

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.
