Been a carman 12 years, but the newer ABDX/DB-60 quirks and updated AAR rules are outpacing what I learned on the job. On third shift last week I chased a 5 psi/min loss after a 90 psi set-and-release to a sticky relay and a hairline crack in a 3/8 service line using an ultrasonic leak detector and a test gauge. What continuing ed or factory schools — Wabtec air brake, AAR refreshers — make you faster at diagnostics, including timing tests and test stand work?
Wabtec’s DB‑60 clinic sharpened my ‘sticky relay’ troubleshooting after 90‑psi sets — worth it; if travel’s tight, REB’s air brake course works?
It’s crazy how one tiny crack can derail your whole day, right? I’ve found that getting hands-on with the diagnostics during those classes really helps solidify the troubleshooting steps. If you can swing it, consider checking out the AAR’s foundational course; it’s a great refresher and can offer new insights on issues like the one you encountered.
