The boat attendants at Maligne Lake were wearing thick fleeces, scarves, hats and gloves so we were glad to find a sheltered place for a picnic after a journey visiting the impressive Maligne Canyon and seeing two bears, several deer and bighorn sheep (extra)
The length of trains crossing Canada from Toronto to the west coast going through the Rockies is amazing and I saw none with fewer than 120 wagons and counted one with 179 doubly stacked containers and sometimes we saw several wagons with ten cars stacked in two layers.    Most were pulled by two locomotives at the front, with one or two distributing the power in the middle and one at the back making them very long. Generally cargo trains are almost 4 km long (nearly two and a half miles long) and need long sidings in which to pass as there are many freight trains using the single tracks.  At one place we watched a train going into a spiral tunnel as the front was coming out hundreds of metres further on and higher above.  This photo is at Jasper Station where three freight trains passed by within 30 minutes.
