Is automatically bringing the train to a stop (including for DCC) achieved just by cutting power to the isolated section of track. If so, does this not bring the train to a very sudden stop?

You are correct. However if the train is running slowly you cannot discern a difference between a sudden and gradual stop. If you want gradual stops with DC then we have the SA7-SB controls. For DCC there are 2 methods you can use. Brake on DC (all chips should conform to this but some Hornby do not) or ABC braking (mostly Lenz chips). The isolation relay on the IRDASC-3 could switch in either of these although you also need the IRDOT-3D for brake on DC to avoid a short circuit on the track.

Hello. So if the block is occupied up ahead or the points haven’t been switched does the train automatically stop then until the block is clear or the points are switched? Many thanks

Yes if you wire in the isolation section. In fact both the block needs to clear and the points switched before the signal goes to clear and the power switches onto the isolation section.
