Possible safety risk?

I took note tonight of a possibly dangerous practise that happens at Clonsilla some evenings. I've seen it happen once last week as well.

The 21:10 Pearse Maynooth is scheduled to arrive at Clonsilla just before the 21:45 Clonsilla M3 Parkway. The latter train waits in the siding just east of the level crossing and then pulls into the platform after the Maynooth train has left.

But what I've seen is that the M3 Parkway train will cross the LC and enters the platform while the Maynooth train is still departing and most of it is still on the platform. A fair distance is maintained between the two trains, but if the Maynooth train were to suddenly stop, a rear end collision is possible- there's no signal protection, it's all based on the reactions of the M3 Parkway driver.

It seems like a big no-no to me to have two trains in the same signalling section(the Maynooth train hasn't cleared the signal at the west end of Clonsilla by the time the M3 Parkway train makes its move).
