I've used Caltrain+clipper quite a lot, the real issues is that there are no gates (no one forcing you to tag out), and not enough readers on busy stations. This is really an investment issue, and with Caltrain not having reliable funding from year to year, we should be glad you can even use clipper on it, because the old paper ticketing system sucked, and I've missed a lot of trains because of it.
