Online / Self Paced Maintenance Skill Training Recommendations

I work with a small but rapidly growing company that desperately needs to begin training a select few employees on maintenance skills. I’m especially interested in pneumatic controls as much of the machinery is pneumatic logic, but there’s a few machines with basic electronic controls and relay logic.

​

Does anyone have experience with online or self-paced maintenance skills training?

The closest technical school that would provide these skills is an hour away from the factory and probably not going to be approved yet.
