Sicily Ferries

Sicily Terminal: (Satellite)
Italy Terminal: (Satellite)

I see there are several ferries between Italy and Sicily. I'm focusing on the railroad ferry.
This is the last train ferry in Europe. A crossing takes about an hour. [medium]
(The train ferry between Hamburg and Copenhagen quit running Dec 2019 when the train was moved to a new, longer route that uses a fixed crossing. A tunnel is being built to restore the shorter route. [rail-away])

Yes, the train to Sicily goes onto the ferry!

John Maguire commented on the above post
Highlight of the trip for me (northbound).

Given the counterweight structure in the background of the screenshot, I believe it is docked where the ferry with the heleport is docked in this image of the Sicily terminal.

Another travelogue

RFI via railtech
Railtech claims the crossing is just 30 minutes.
It is hybrid-powered and will have zero emissions in the port.
"The new ship is 147 metres long and 19 metres wide and has a maximum capacity of 27 rail wagons on 4 tracks. It can accommodate 700 people, including the crew. Iginia will join RFI’s fleet of ships between Messina and Villa San Giovanni, together with its sister ship Messina, Villa and Scilla, and the five ships of the Bluferries subsidiary."

I just skimmed this video.

"This elegant span, with its handsome profile stretching 67 meters [220'] above the Ringdalsfjord, is Northern Europe's highest bridge. The Svinesund Bridge was opened with great ceremony on 15 June 1946, by the Norwegian king and the Swedish crown prince. The traffic has increased over the years, and at the end of last century it was decided to build a new highway and bridge between Norway and Sweden. June 10th 2005 the new bridge opened between those two countries."

"The Svinesund Bridge is a through arch bridge crossing Iddefjord at Svinesund and joining Sweden and Norway. It was completed in 2006. The bridge is 704 m long and has a clearance high of 55 m [180'] above the water."

"Arching 302 ft. (92 m) above the Iddefjord between Halden, Norway and Strömstad, Sweden, the Svinesund bridge opened to traffic on June 13, 2005....The arch is hollow, and employs heating coils to prevent the buildup of snow and ice. It also contains interior maintenance pathways to simplify access for the bridge’s upkeep."

This photo shows that the approach on the Sweden side is non-trivial.
"The bridge features two separate lanes for automobiles, as well as a dedicated lane for bicycles and pedestrians."

This view shows its use of granite for the facing of the 1946 bridge.

Note that the bridge drawfs the houses down by the river's shore.
"The bridge is 420 meters long and the main span is 155 meters. The bridge was protected by Directorate for Cultural Heritage who believed that the bridge is a symbol for the connection between Norway and Sweden" To use the ferry before this bridge was built meant that you had to go down into the valley and then climb back out of it.

"The construction of the arch used a climbing formwork and the cable-stayed cantilever construction method known as the ‘Freivorbau’ technique. Using this method the arch is temporarily supported during the construction by cables that are anchored to auxiliary towers. The two towers are securely back-anchored in the rock using high tensile steel cables and are then dismantled following the completion of the arch."

The deck has two steel box-girders tied together with cross girders.

Cracked and Replacement Spitallamm (Grimsel Pass) Dams in Switzerland

(Satellite, the image is too old to show the replacement dam)

Adriano Gabaglio, Jul 2023

While watching another video, Facebook flipped this video in front of my eyeballs. I watched it because it was interesting. And this scene caught my eye because it appears that is a woman that is holding a consolidator. (Vibrator is a common term for that equipment, but I was afraid of typing a phrase that would trip some AI big brother in Facebook.) In America, if I see a woman on a construction site, she is typically holding a traffic control sign. In fact, I heard one complaining on her cell phone about how long would she have to do the entry level job before she could do something else. (Of course, if she was doing something else, she may have to give up do personal calls while working.)
4:43 video @ 2:22

The narrator of the above video never disclosed the name of the dam nor of the location. Fortunately, the Google search of "switzerland 140 million dollar dam project" provided some useful results.

"The Race to Replace a Cracked Dam
"Spitallamm is one of the world’s first large arch-gravity dams. It was built up in the mountains between 1925 and 1932 and is actually older than the Hoover Dam, which completed three years later. At 114 metres [374'], Spitallamm was also one of the tallest dams in the world when it finished."
[The web page has a 24:40 video, but I didn't watch it because it started with a talking headk and because the 4:43 video is very informative.]

Note that the old dam is still peaking over the top of the new dam.

The powerhouse is under the reservoir and a tunnel is used to access it.
[I was unable to find megawatt capacity of this powerhouse.]

1992 Osceola and St. Croix Valley Railway

Osceola and St. Croix Valley Railway is a tourist railroad that is a wholly owned subsidiary of the Minnesota Transportation Museum (MTM) and the Osceola Historical Society. It runs excursion trains from Osceola, WI, to Marine on St Croix, MN, and to Dresser, WI. It also has operating rights to Withrow, MN, which it uses for special trains throughout the season. [4:28 video]

The MTM offers a variety of train rides.

At least one exhibition train includes a demonstration of a RPO snagging a mailbag.

This railway runs on what was the original SOO/Wisconsin Central mainline until the 1980s.  Now CN runs just one ballast train a day that hauls rock from a quarry in Dresser. This ballast train was captured before Canadian Pacific sold the SOO line to Canadian National.

The railroad has preserved freight cars as well as passenger cars. And some train rides cross the St. Croix River on this 1887 swing bridge, which no longer swings.

2002 Busan Gwangan Bridge around Busan, Korea

(Satellite, 3,910 photos)

Street View, Dec 2017

Construction started in 1994 and it was completed in Dec 20002.

Rather than tear down a bunch a buildings and divide a city, they just went around it.

LuNaR Lee, May 2010

The bridge is a double decker with four lanes on each deck.
Street View, Dec 2017

"The Busan Gwangan Bridge is 4.6 mi (7.4 km) long, and the Length over water is 2.7 mi (4.4 km ). It is a double-layer bridge. The upper part leads to Namcheon-dong and the lower part leads to Centum City. There are 4 lanes on each floor, a total of 8 lanes. It consists of 3 parts, among which the suspension bridge is 2953 ft (900 m) long, the truss bridge is 2362 ft (720 m) long, the connecting bridge is 3.6 mi (5.8 km), the width is 18m-25m, and the height from sea level to the roof is 115 ft. (35 m)....The bridge is equipped with thousands of LED lights, making its night view very beautiful. An annual Guang’an Bridge walking competition is held." It cost 789 billion won (US $710 million).

Korea likes pedestrian suspension bridges, but this would be the annual walking competition.
Highway Engineering Discoveries posted

In 2019, a 370'-long Russian cargo ship allided with the bridge. The captain was drunk and tried to flee the scene, but the Korean Coast Guard blocked the ship and shepherded it back to port. "The Seagrand had also struck a cruise ship in the port about 40 minutes before the bridge incident, according to authorities." "A KCG official said that it is not illegal for a captain to consume alcohol onboard the vessel as long as they are not at the helm." [newsweek] But I gather from a report of a grounding near Baltimore, MD, that the captain should be present when a ship is leaving a port. That would be especially true if your crew has already banged into something on the way out.

2:45 video @ 0:37
[Note from the propwash that the ship was still pushing forward. Soon after, the propwash changes because it was finally put in reverse.
The cars didn't even stop. If I saw a big ship coming at a bridge I'm on, I think I would stop well before the collision point to see if the bridge wins the battle.]

Two Tourist Suspension Bridges in Korea

400 Meters Long: (Satellite)
204 Meters Long: (Satellite, 21,477 photos! I think that is a new record.)

From what I can tell, the 200m long hanging bridge that we see on the left side of this photo has proven to be such a popular tourist attraction that they have expanded the attraction by building a trail system that now includes the 400m long suspension bridge near the right side of this photo. I'm using lengths to identify the bridges because I have seen multiple, similar names for the two bridges.

"One of the main attractions of Wonju, Sogeumsan Suspension Bridge is the longest and largest pedestrian bridge in Korea with a length of 200 meters, a height of 100 meters, and a width of 1.5 meters. The thrill of walking midair is enough to make visitors come to this attraction. The skywalk next to the bridge offers an amazing view of the surroundings. With a protective deck at the entrance of the bridge, anyone who has the courage can walk on the bridge."
[They need to update their website because the other bridge is over twice as long as this one.]



You have to pay to use this 404m long bridge.

I think access to the Sky Tower and Cliff Walk is part of the admission fee.
"A cliff walk attached to the cliffs face of Sogeumsan Mountain like the one at Zhangjiajie of China. An observation deck which provide a bird eye view over the whole Ganhyeon tourist site from 150 meters above the ground."

When in Korea posted
Wonju Sogeumsan Bridge. The longest mountain bridge in Korea.

Pedestrian suspension bridges seems to be a thing in Korea. This site lists 11 of them, including the 200m Sogeumsan Suspension Bridge. The 200m bridge is called the Sogeumsan Suspension Bridge, and the 404m bridge is too new to be in the list.
