カンボジアに無事到着しました。プノンペンより投稿しております。なお、カンボジア関係につきましては、別のブログを立ち上げたいと思っております。
さて、本題です。
You Tubeに、雪景色のカスケード越えの動画が投稿されました。

カテゴリーは、「音楽」なので、背景ということでしょうが、結構楽しめます。なお、最初のシーンは、機関車からとっているのではなく、列車の一番後ろからとったものを逆回ししたものです。
なお、同じ人が投稿したものが他にも２本あるとのことです。（まだ見てません）

ご参考までに、最初のビデオの説明（英文）を転載します。
The music is from Enya "A Day Without Rain" & Dave Carter and Tracy Grammer "Little Liza Jane"
"Little Liza Jane" if from an amazing cd called"Drum Hat Buddha" from Dave Carter and Tracy Grammer - every song on it is... awesome - is the only word that comes to mind. Before Dave left us, he left these gifts - Do yourself a favor and search for Dave Carter & Tracy Grammer - and buy all 3 CD's - iTunes has double samples of all their songs.
The Cascade Tunnel is a 7.8 mile (12.5 km) long single track railroad tunnel at Stevens Pass through the Cascade Mountains approximately 65 miles to the east of Everett, Washington. It is the longest railroad tunnel in the United States. It was built by the Great Northern Railway in 1929 at a lower elevation than the original, 2.6 mile (4.2 km) tunnel which had suffered problems with fumes, itself built to avoid problems caused by heavy winter snowfalls on the original line which had 8 Zig Zags (switchbacks). It is currently part of the BNSF Railway system on their mainline between Seattle and Spokane. Amtrak's Empire Builder runs through it.
The first tunnel had a fume problem because it was built too steep and too close to the ruling grade. The tunnel was electrified by 1909, which eliminated the fume problem.
The second Cascade Tunnel was constructed between 1925 and 1929 to replace the shorter, higher-elevation tunnel which was still plagued by snowslides in the area. The new alignment is a straight-line tunnel running between Berne and Scenic. The gradient in this tunnel is 1.7% (1 in 58) with the rise from west to east. The railroad line was electrified between Skykomish and Wenatchee. New electric locomotives were used in this portion which were again powered by overhead catenary.
In 1956 the electrification was removed. However the great length of the tunnel plus its steep gradient meant that the fume problem resurfaced. So a ventilation system was provided. As a train enters the east portal of the tunnel, doors close behind it and huge fans blow in cool air through a second portal to help the diesel engines. As long as the train is within the tunnel, the fans work with reduced power to avoid pressure problems. After the train has left the tunnel they operate for 20-30 minutes with maximum power to clear the tunnel of exhaust before the next train passes through. In the opposite direction the door opens when the train is about 1000 m away from it. Present-day train crews carry portable respirators for use in the event of a fan failure or a train stalling inside the tunnel. In addition there are stations spaced every 1500 and 2500 (based on location in tunnel) that provide additional air tanks and equipment to be used in the event of a failure.
