My understanding is that the crush risk at Euston is entirely an operational issue of Network Rail's making (NR being the station facility owner), by deliberately not announcing platforms until the last moment, causing passengers to run to the platform en masse. If platforms were announced earlier, the crush risk would be seriously mitigated.
The obvious next question is whether platforms _can_ be announced earlier - to which the answer is, as I understand it, yes. The platforms are known about much further in advance and the reason for the delay appears to be a combination of intransigence by Euston management and a lack of sufficient ticket gateline staff by the train operators.
