I'd give it a couple of years and see if there are more runs of certain locos.
Obviously, some people will say that they'll never be run again, other will ignore the economics and say that there should be X, Y and Z run tomorrow, but striking a balance between those two poles, re-runs are an inevitability.
There are a couple of 141's for sale at €250 each on adverts.ie at the moment, but that's far too much, in my humble opinion. Not saying that they won't sell, they definitely will, but as the 121's and A's show, €190 is what a brand spanking new loco with all of the current features is worth.
I hope you've ordered yourself a few A's???
