We were blessed to recieve free tickets for a 3 hour excusion on this railway, sorry railroad, from Skagway to White Pass summit (the Alaska/Yukon border) The journey was excellent though some of the finest scenery I have seen. I took about 150 photographs, but many were useless due to the necessity to hang on the the handrails and try and photograph as the train clanks and lurches up the gradient. You needed to hang on as the handrail on the open ends of the car is about 3 feet high and the drop from the trackside upto 1000 feet, sharp corners and old narrow gauge track make matters worse.
Getting on at the railroad depot (railway station to you) was different. They don't use platforms, but have steps that lower down from the carriages.
The train, headed by three Co-Co diesel electric locomotive in tandem started the 20 mile 3000 feet climb from Skagway hauling 12 coaches. Here it is at about 5 miles out. You can tell how twisty the track is - the photograph was taken from about the 5th coach back.
The above photograph was taken from about the same location as the above one showing the track, tressle bridge and tunnel just 1 mile ahead, and to the right is the same bridge and tunnel.
Approaching the top of the pass the original "Trail of 98" can be seen running parallel with the railway. This was the original path that the goldseekers walked from Skagway on their way to the Klondike goldfields in 1898.
At the top of the pass, just over the official Alaska/Yukon border is the place where we turned around. The line disappears around the corner heading for the Canadian customs post at Fraser BC and then on to Bennett Lake, 40 miles from Skagway. The rest of this once 110 mile long line is now disused, although the track is still down. We saw this at Robinson where we stopped on the way to Whitehorse and near to Whitehorse itself where the line formerly terminated.
Coming back from the summit the views got even better, although all the previous mentioned problems of photography had a new addition -  Braking! As the locos braked, the cars now had this added handicap. Things were not helped by the view below this point of an old rusty wreck of a few train like shapes some 500 feet down the slope.
The opposite view, taken from the line below the tunnel shows the Skagway to Whitehorse road (horizontal line on the far hillside) and the line of the lower reaches of the railway, the cutting in the trees on the left hand hillside, about half-way down.

Built in 1898 during the Klondike Gold Rush, this narrow gauge railroad is an International Historic Civil Engineering Landmark, a designation shared with the Panama Canal, the Eiffel Tower and the Statue of Liberty.

The WP&YR railway was considered an impossible task but it was literally blasted through coastal mountains in only 26 months.

The $10 million project was the product of British financing, American engineering and Canadian contracting. Tens of thousands of men and 450 tons of explosives overcame harsh and challenging climate and geography to create "the railway built of gold."

The WP&YR climbs almost 3000 feet in just 20 miles and features steep grades of up to 3.9%, cliff-hanging turns of 16 degrees, two tunnels and numerous bridges and trestles. The steel cantilever bridge was the tallest of its kind in the world when it was constructed in 1901.

The 110 mile WP&YR Railroad was completed with the driving of the golden spike on July 29, 1900 in Carcross Yukon connecting the deep water port of Skagway Alaska to Whitehorse Yukon and beyond to northwest Canada and interior Alaska.

White Pass & Yukon Route became a fully integrated transportation company operating docks, trains, stage coaches, sleighs, buses, paddlewheelers, trucks, ships, airplanes, hotels and pipelines. It provided the essential infrastructure servicing the freight and passenger requirements of Yukon‚s population and mining industry. WP&YR proved to be a successful transportation innovator and pioneered the inter-modal (ship-train-truck) movement of containers.

The WP&YR suspended operations in 1982 when Yukon's mining industry collapsed due to low mineral prices. The railway was reopened in 1988 as a seasonal tourism operation and served 37,000 passengers. Today, the WP&YR is Alaska's most popular shore excursion carrying over 300,000 passengers during the May to September tourism season operating on the first 40 miles (Skagway, Alaska to Bennett, B.C.) of the original 110 mile line.
