Abstract：Research purposes: The train test line in metro depot is used for train dynamic debugging and test. New trains and the repaired trains must be debugged and tested on the test line before service operation. The test line should be proper on the length,curve radius，grade , etc , but that is difficult to get , as the restricting of area. It should be emphasis that determine of function requirements and optimizing scheme of test line on the design of metro depot.
Research conclusions: The test line in metro depot is necessary and important to ensure safety and reliability of train operation. The teat line should be designed to meet the highest operation velocity test if site is available. When the site area is restricted, we should propose to determine the test line design standard according to the class of depot, and necessary high velocity teat can be carried out on main line.
