This is something that has occurred to me lately. I'd like to be able to model Irish Rail as things are today.
I have some wonderful Spoil Wagons and Tara Mines wagons, but no passenger stock at all, no 22000's, no CAF Mk4's, no Enterprise coaches, nothing.
On top of that, sourcing locos to haul them was very difficult. No 071's available, and the 201's were hard to find and cost above average.
I'm not going to give up, and will probably settle for some BR Mk4 repaints with no DVT, along with some 071 repaints in pre-2015 condition, but deep down, that won't truly satisfy me.
