It's very hard to find a source of a radio signal sent from a middle of nowhere (having only a few trains to trinagulate). Of course we should do this, but if someone starts abusing this to raise chaos in the country, we may have no other choice. And we have an enemy country very interested in causing problems nearby.

Not right now, but since 2009 we're implementing GSM-R, and we still don't have it. It's not a bad solution, but nobody really cared until the recent abuse happened.

Legacy... hard to overcome that in a few years when it took many, many decades to deploy the original gear. This stuff is quite expensive, deployed everywhere and needs to continue to be backwards compatible while the new solution is rolled out, which is difficult to achieve.
