By default, Railroader reports as much as possible. Because there is no way for Railroader to know if certain items are actually safe or not, it errs on the side of reporting too much rather than possibly not reporting a real problem. Sometimes, though, these false positives can become overwhelming. Railroader does provides many options for customizing reports. It is also possible to ignore specific warnings.
It is recommended to always run Railroader with the default settings first (and then periodically after that), but it is possible to narrow down the results to make them less annoying.
