[openrailwaymap] Lifecycle tagging: tram or rail?

Greetings! - new member from the US here. I'm going through and fixing abandoned and razed railways that I added in the past, making sure that the lifecycle tags "abandoned:railway" and "disused:railway" are present and accurate. One annoying issue that I can't resolve - what to tag when a route formerly featured tram AND freight operations. Does "rail" serve as the hierarchical top level, so that if the line operated as a standard rail line at any time, any other service is ignored? I'm assuming that a tag of "rail;tram" is not acceptable. Thanks! GR
