USC tram to Union Station... operate on holidays?

<p>Does anyone know if the USC tram to and from Union Station operates on Mondays during those many three-day weekends/holidays? I just "discovered" the TrojanTransportation website, and USC's tram system looks very impressive! Because I was thinking about the convenience (I live in SoCal) during a few of the long weekends of maybe taking the train on Friday, and heading back to USC on Monday (the website just says Monday-Friday operation with the times, nothing about the dates and holidays). Thanks!</p>
