Tips for Diagnosing Engine Vibrations

I’ve been dealing with persistent vibrations in a locomotive engine lately, and it’s proving to be quite the challenge. I started by checking the mounts and ensuring everything was secure, but I’m wondering if anyone has specific diagnostic techniques or tools they find helpful for isolating these kinds of issues. Any insights would be great.

I had luck using a stethoscope to pinpoint noise sources. It helped isolate vibration issues, especially near the crankshaft. Have you tried that?
