The NER Class 3CC (LNER Class D19) was a 4-4-0 steam locomotive designed by Wilson Worsdell for the North Eastern Railway and built in 1893. Only one was built (number 1619) and it was a compound expansion version of the simple expansion NER Class M1. The 3CC was originally classified "M" but was re-classified "3CC" when the M1 was re-classified "M".

Overview

Number 1619 was built as a Worsdell-von Borries compound with two inside cylinders. It later became a test-bed for the development of Walter Mackersie Smith's ideas and, in 1898, it was rebuilt as a three-cylinder compound with one inside high-pressure cylinder and two outside low-pressure cylinders.

Classification

Aside from its compound expansion, the 3CC was similar to several other NER classes and they are summarised here:

Original NER class	New NER class	LNER Class	Cylinders	Driving wheels
M1	M	D17/1	(2) 19" x 26"	7' 1¼"
Q	-	D17/2	(2) 19½" x 26"	7' 1¼"
Q1	-	D18	(2) 19½" x 26"	7' 7¼"
M	3CC	D19	HP (1) 19" x 26" LP (2) 20" x 24"	7' 1¼"

• HP = high pressure cylinder, LP = low pressure cylinders
• This table shows the cylinder dimensions of no. 1619 in 3-cylinder form. The cylinder dimensions in 2-cylinder form are not known

Legacy

Number 1619 was a one-off but W. M. Smith went on to develop a four-cylinder compound system in the NER Class 4CC (LNER Class C8) 4-4-2 locomotive. Number 1619 was withdrawn in 1930 and was not preserved.

Smith's three-cylinder compound system was also used in the Great Central Railway classes 8D and 8E (LNER Class C5) 4-4-2s and achieved its greatest success in the Midland Railway 1000 Class and the LMS Compound 4-4-0.
