No. 116 was built in 1903.

No. 116 originally had a 4ft-8in diameter boiler, as fitted to the Long Tom 0-8-0s (Class K1).  It was hurriedly given a replacement 4ft-2in diameter boiler, which was part of an order intended for Stirling single-wheelers.

Balance weights were not incorporated in the coupled wheels.  Its cylinders were lined up to 18in in November 1905, in line with No. 120 of the 117 Series (see below).

No. 117 SERIES

LNER CLASS R1

4ft-8in wheels, cyls 19¾in x 26in, Gresley Dgm 12 boiler

General Plan dwg Q63 (27/10/1903) for No. 116 as originally built
General Plan dwg Q64 (13/1/1905) for Nos. 116-56 with smaller boiler

Nos. 117-26 were built in 1904.

These had the larger size of cylinder which was more in keeping with the originally intended large boiler.

These engines and later batches had balance weights in the coupled wheels.  As they were built with smaller boilers then originally intended, it was decided to reduce their cylinder diameter.  No. 120 had its cylinders lined up to 18in diameter in June 1905.  The remaining engines of this Series, i.e. Nos. 117-19/21-26, were fitted with new 18in diameter cylinders (between May 1906 and February 1907).  The nine original cylinders were salvaged and reused for new 0-8-0s Nos. 445/46/44/42/41/47/49/50/43.

4ft-8in wheels, cyls 19¾in x 26in, Gresley Dgm 12 boiler

Nos. 127-36 were built in 1905.

These also had the large cylinders.  They had new boilers to match the one fitted in a hurry to No. 116.

They were allowed to retain their original 19¾in cylinders, perhaps because these engines were destined for Nottinghamshire and the West Riding.

No. 137 SERIES

LNER CLASS R1

4ft-8in wheels, cyls 18in x 26in, Gresley Dgm 12 boiler

Nos. 137-56 were built in 1906.

Their cylinders were reduced in diameter.

BOILER SIZE

No. 116 was built with a 4ft-8in diameter boiler (as fitted to the 0-8-0s) which was then banned by the Civil Engineer for working over the Widened Lines.  It was hurriedly given a second-hand 4ft-2in diameter Stirling-type boiler, the side tanks were shortened to reduce still further the excessive weight and the cab was lengthened.  This new arrangement was acceptable and the later engines of this class were given similar smaller (but brand new) boilers.  One difference between No. 116's replacement boiler and the ones fitted to Nos. 117 onwards, was the former had a three-ring barrel whilst the latter had two rings conforming to current practice.  Also, their firebox casings were 1in wider, at 4ft-0½in.  In 1905 new engines were sent to the Yorkshire and Nottinghamshire areas for goods and mineral traffic, followed afterwards by examples from the later engines. 

The position at the end of 1906 was that there were 40 "new" boilers plus one "Stirling" boiler.  There were no spares, though if necessary there were still three boilers left from the March 1901 "Stirling" boiler order which could be used.  But one of the spares was used in 1907 for Class A3 4-2-2 No. 1007 and another was taken in 1910 for Class B3 2-2-2 No. 872.  This left just one spare, which was eventually fitted to No. 128 (December 1910).  It seems strange that No. 128 was not given a larger boiler instead but perhaps there was none available.

Meanwhile in 1909 No. 133 was given a 4ft-8in diameter of the same type originally fitted to No. 116 and this proved a success, though not such as to justify any more being altered for the time being.  This was probably on the grounds of cost.  It required the costly construction of forty 4ft-8in diameter boilers displacing a like number of 4ft-2in boilers for which there was no foreseeable use.  So it was a further three years before a start was made dealing with the remaining engines.  From August 1912 the engines were gradually fitted with 4ft-8in boilers, though the work was not completed until August 1926.  This process left a glut of spare 4ft-2in diameter boilers with little hope of further use, (but see Class J23 0-6-0Ts).

SUPERHEATING

Nos. 129/31/35/36/38/48/49 were fitted with superheaters (1914-20), which was now feasible once a start had been made fitting 4ft-8in diameter boilers.

LNER

LNER Class R1 was intact at Grouping : 41 in service, including 3 still with smaller boilers

LARGER BOILERS

The last three with smaller boilers were brought into line : Nos. 130 (9/1923), 132 (1/1923) and 3154 (8/1926).

WITHDRAWALS

The engines were withdrawn between December 1927 and February 1934, the last of the Class being No. 3154.
