潤滑概述

部分車輛傳動系統 有著如汽閥機構，必須不間斷受到潤滑才能正常運作。此在蒸汽機車 上非常普遍。

Such vehicles typically carry oil in an onboard storage. The available reserves are shown on the left meter of a device called an automatic lubricator .

This device lubricates some of the bearings that it can reach, while the rest needs to be lubricated manually .

If a vehicle has been sitting parked for a while, it is likely to have dry bearings, due to leaks.

If any of the lubrication systems are lacking oil, the drivetrain will produce unpleasant screeching noise. If no action is taken it may quickly result in catastrophic damage to the drivetrain.

If the oil storage runs dry it needs to be refilled .
