Questions

How big is the BlockModule1speed PCB?

It measures 75 × 25 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BlockModule1speed use?

16 parts, built around the EL814 and BC547. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the BlockModule1speed KiCad files?

From the bask185/Train-Science-DIY repository on GitHub, at the commit this page was made from: the board is PCB_SOURCE/analog_solutions/CabControl/BlockModule1speed/BlockModule1speed.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the BlockModule1speed design in my own project?

Its repository states no licence, so its author keeps all rights: ask bask185 before reusing the design.
