Why do train spotters get so excited about it?  All I can think of is that many model railways have hills where the model train goes in one entrance and pops out of another and I suppose the rail buffs see this as something they had on their model layouts.  We will go through the tunnel ourselves on the last leg of our holiday but unless we are in the first or last carriage we won't see the other end of the train. 

After that lack of excitement we visited the Takakkaw Falls, some of the highest in Canada and very good they were too even though we have our backs to them.

We are now in Revelstoke, a railway town in the middle of the Rockies.  It has a railway museum which we hope to visit tomorrow and a spectacular National Park which we won't! Why? Because there are over 10 forest fires raging in the park at the moment so it is closed to visitors, sitting in our hotel room I can smell the burning even though the fires are quite a long way away, I do hope they don't get too close.
