P092-20 almost 5 hour delay SBG-WTH - Why?

According to the web site, it apparently lost 4.5+ hours between SBG and WTH. Anybody know what happened? That segment should be about 40 minutes but took 'em almost 5 and a quarter hours today.

I'd put money on an engine failure or grade crossing incident, either one is a good bet.
