The direct railway route from A to B is not always the best. If the gradient is too steep, an additional loop (or a cogwheel section) is an advantage. Around 1906, for example, the engineers used this spiral-shaped track guide to build the Bernina Railway below Brusio in order to gain height at a maximum gradient of 7.0 %. Train 4672 from Tirano to St.Moritz is running through the spiral and crossing the 142 meter long Brusio viaduct at 6 PM, drawing an impressive track of light through the landscape. On the right the light traces of cars on the road through Brusio, with some stars of the christmas lights. A 171 seconds exposure.
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!)
