Not really - it takes no training to make a phone call. Consider that the phone call about the actions (or mere presence even in legal proximity to a rail facility) of a fan could be based not on training but on a) (for a quasi or actually legitimate complaint) common sense or general training regarding treaspassers having nothing to do with "terrorism" or b) (for the rest) paranoia based on anything from a perceived threat to buying into media hysteria that al queda members are lurking under every third rock.
While I strongly support the rights of railway companies to protect themselves from treaspassers or worse, there have been enough documented cases of over-reaction to legitimate railfanning to warrant concern and, indeed, a need for true training of rail employees (including, especially, railroad police). Given the combination of our free society and technology, the real threat is unlikely to come from someone taking a picture or watching a train roll by. If someone has evil intent, there is enough easily observable or publicly obtainable information about most modes of transport, including trains, for them to accomplish their goals.
The current firestorm surrounding the christmas eve bomber on the flight from europe only reinforces this. People that want to be assured that they are at "no risk" should neither use any form or public transport nor come out of their steel reinforced concrete bunker to shop. It's not an attainable goal and I, for one, don't want to endure that which would be necessary to get us even close attaining it.
