Is there anything left to do at these iconic locations that hasn't been done before? Well, until you've been there yourself and shot it your way, yes! I love night photography. I have so much more control over what I want to emphasize. Morant's Curve isn't the darkest spot - in fact there's a lot of light pollution from Lake Louise and the Trans-Canada Highway not far away that lights up the clouds. But along the Bow River, down among the trees, it's still pretty darn dark - until a train comes. For a few seconds every couple of hours, the riverside is flooded in light as a the headlights sweep left across the dark pines, then down the river, then swing back to the right, reflecting off the snow and revealing the track and surrounding wilderness ahead to the engineer.
Landscape photography is difficult due to the challenge of combining good light and good scenery. Good railroad photography enters another level of complexity since it requires the first two while there is a train in view.
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
