"I'm going home right now" is ok, but the other two sentences are hard to understand. Did you go for a drink after work? Was your train crowded? "Crowned" does not make sense, I guess you mean "crowded", which you can use (as an adjective) to talk about a train with many people on it. The verb "to go" can be "go, goes, going, gone, went", but not "gong". "Gong" is another word, I don't think that's what you mean.
