The direct route from A to B is not always the best. If the gradient is too steep, an additional loop 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.
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!)
