I agree with those of you who like Class 91 & Mark 4 trains, alas largely withdrawn now. These have been my favourite Inter City trains.

As regards EMUs, my favourites have been 317s and 350s. For DMUs I think I prefer 156s to 158s, but this might be because 158s have been disproportionately crowded on their routes. I prefer 185s to 170s and therefore hope they are all redeployed in the end.
