Help in creating a new simple train newGRF

Hey everyone,
I'm looking for a couple of pointers on how to create a very simple newGRF centered around trains. Ideally I'd only modify the default trains slightly (names, speeds), and add new trains to the roster using the default available sprites.
I know how to code and looked at NML already, but I'm at a loss about how to handle sprites, where to get them, or how to compile a newGRF and what files are needed.
I'd appreciate even very simple directions on how to start, a working example with a single train that uses existing graphics would be perfect for example!

Thanks man. Where would I find the default graphic files? I can't seem to find .bmps either in the OpenTTD directory or the OpenGFX+ repo.

After compiling the code, the .png files are no longer accessible. I presume with "default graphics" you mean the graphics of the standard OpenTTD trains and such. That'd be these:

Thank you, this really helps get me started!

I managed to replicate the Kirby with my newGRF. How would I go to remove the old trains from the list when my grf is active?
