- Coal Engine 0-6-0 Locomotive Class
- In February 1873 Mr. Webb
introduced the famous 17in Coal Engines, the first new engine he was entirely responsible. The design was based on that of the ‘Special Tanks’ and at first used the same boiler up rated to 140 psi ; later the whole class had boilers with larger fireboxes . The first batch had Ramsbottom safety valves but Webb chimney, cab, coupling rods and cast-iron wheels. The horizontal smoke box door, wooden buffer beam and brake blocks , absence of brakes on the engine and the style of the 1,500 gallon tender with grease axle boxes all date from the earliest Crewe designs , well before Ramsbottom .

- Coal Tank 0-6-2T Locomotive Class
- 0-6-2T tank engine
version of the Webb 17in Coal Engines , first introduced in 1881. Although intended originally for goods and shunting duties, in fact they proved very suitable for local passenger train work.
