NER Class 3CC
Encyclopedia
The NER Class 3CC 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".

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.
. Number 1619 was withdrawn in 1930 and was not preserved.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

and built in 1893. Only one was built (number 1619) and it was a compound expansion
Compound locomotive
A compound engine unit is a type of steam engine where steam is expanded in two or more stages.A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger...

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
