A lubricant level monitor for gear covers of locomotives uses a vacuum probe tube to determine if the lubricant is below a predetermined level. The vacuum is only activated if the locomotive has been at rest for a predetermined period of time, so that the lubricant has time to settle. The monitor employs a minimal amount of electrical devices and uses pneumatic logic wherever possible insure trouble-free opera- tion. The monitor eliminates the requirement of inspection personnel going beneath the locomotive, and it eliminates the need for the locomotive to be arbitrarily pit-inspected every two weeks for a lubricant level check.
