so there will be multiple new classes, some of the classes are named, but i need your help coming up with names, the classes are as follows

C2 4-4-0 100 locomotives

Named after creatures of earth's mythology, and natural species of Equestria and it's lands beyond

J1 4-6-2 50 locomotives

a variety of topics

J3/1 4-6-2 50 locomotives

I'm thinking any name that conjures an impression of speed

J3/2 4-6-2 50 locomotives

More speed!

L1 4-6-2+2 50 locomotives

even more Speed!

O2 2-8-2 50 locomotives

Nautical stuff

S1 4-8-2 50 locomotives

The theme for this class is "Leaders"

C3 4-4-0 30 locomotives

Compounding proved popular on the Midland Railway in Britain, but very few Equestrian railways followed suit. The C3 was inspired by this and proved very successful, some running for as many as fifty years.

C4 4-4-0 40 locomotives

Named after schools in Equestria, and considered the most powerful of its wheel arrangement in Equestria. A 4-4-4T example, classified G1, was just as successful and ran many services of the same kind.

I2 4-6-0 10 locomotives

One of the last inside-cylinder locomotives in Equestria, and one of only two classes of its wheel arrangement as such, the I2 consisted of locomotives named after cities on its route.
