Diesel Train in the Royal Gorge

Postcard US-3689818 to Russia shows a diesel train in the Royal Gorge, on the Arkansas River, passing underneath the Suspension Bridge - "The World's Highest Bridge", near Cañon City, Colorado, Cañon City, with a population of 16,400 as of 2010 and known as the "Corrections Capital of the World for having nine state and four federal prisons and penitentiaries, is one of the few U.S. cities that have an eñe in its official name.

Two train stamps, among others, were affixed to the card. One was a 33-cent "The Congressional of the Pennsylvania Railroad" from a set of five 1999 stamps entitled All Aboard! 20th Century American Trains. The other “Untitled (Trains on Inclined Tracks),” showing a gouache, colored pencil, and graphite drawing on pieced paper from circa 1960–1963, was one of the five Forever stamps, issued on March 26, 2015, featuring the work of Mexican artist Martín Ramírez who had been confined to psychiatric hospitals for more than 30 years.

I had the sender's address since November 6, 2015. However, the card didn't get posted until December 4, 2015 due to delay from my training for my first half marathon and my encounter of a failed armed robbery. The card had since expired after 60 days, and it was automatically registered by Postcrossing on May 11, 2016 when the account of the receiver was closed.

Trump International Hotel

Real estate developer Donald Trump is poised to become the presumptive Republican presidential nominee after his decisive win in Indiana, which led Ted Cruz to drop out of the race.

Named for the real estate developer, the property is distinctive as the exterior windows are gilded with 24-carat gold.

Walking over the Golden Gate Bridge

It was a little windy but otherwise beautiful earlier today. I took the opportunity to walk across the Golden Gate Bridge in San Francisco - one of the most beautiful bridges in the world, and back, as part of my Coastal Trail hiking. The bridge celebrated its 78 anniversary of opening on May 27, 2015.

The bridge spans 2.7 kilometers or 1.7 miles. I started at the parking lot on the San Francisco side. During my previous visits, I had turned around at the first tower like most people did. However, walking over the full span turned out very rewarding. From the Vista Point in Marin County on the other side, you got to see the entire northern coastline of the city including the Fisherman's Wharf area. The added bonus was watching those large container and cargo ships passing directly under the bridge. It took me a little bit more than one hour for the 6.1-kilometer or 3.8-mile round trip.

"CSL TECUMSEH", a 2013 self discharging bulk carrier sailing under the flag of Bahamas, was passing the bridge.

Postcard US-2849047 to Finland shows an aerial view of the Golden Gate Bridge with an ocean cargo ship passing by.

Burg Giebichenstein und die Giebichensteinbrücke

Postcard DE-3903996 from Germany shows Giebichenstein Castle and the Giebichensteinbrücke bridge in Halle (Saale), an economic and educational center in eastern Germany, located in the southern Saxony-Anhalt state.

Giebichenstein Castle, seen on the right on the postcard, was a royal residence of Otto I, Holy Roman Emperor in the 9th century. It is used by the Kunsthochschule Halle (Academy of Arts) of the Burg Giebichenstein Art School.

The Giebichensteinbrücke bridge, also known as Kröllwitzer bridge, is one of three Saale River crossings in Halle, located in the north part of the city below Giebichenstein Castle. The Giebichensteinbrücke bridge in its current form was built between 1926 and 1928 as a replacement for a steel bridge with large truss arch from 1892. The bridge's main arch was blown up during the final days of World War II on April 14, 1945. It was re-built in 1949 and renovated from 1993 to 1995.

On February 13, 1990, an agreement was announced on a two-stage plan to reunite Germany.

Wuhan by Ferry

Postcard CN-1520549 from China shows people taking ferries to cross the Yangtze River in Wuhan, Hubei Province, China. Wuhan (武汉), the capital of Hubei province and the most populous city in Central China, is located at the intersection of the middle reaches of the Yangtze and Han rivers, consisting of the conglomeration of three cities, Wuchang, Hankou, and Hanyang.

Those three cities face each other across the rivers and are now linked by bridges, including one of the first modern bridges in China. Ferries were the only transportation to cross the rivers before the Wuhan Yangtze Great Bridge opened in 1957. Even after the Metro Line 2, the first Metro line crossing through Yangtze River, opened on December 28, 2012, ferries remain a best choice for going directly across the Yangtze River since it's inexpensive and quick, and you can take your bicycle to the ferry for a nominal fee.

In addition, it's a scenic ride to see the rivers and skylines of the three cities. Many ferry terminals for the more than dozen ferry lines are located by the Snake Hill in Wuchang where the Yellow Crane Tower (黄鹤楼), a historic tower first built in 223 A.D., overlooking the Yangtze River.

Love Locks and the Pont des Arts

Postcard SG-157009 from Singapore shows a loving couple at the Pont des Arts, a pedestrian bridge which crosses the River Seine in Paris, France. It was first built between 1802 and 1804, under the reign of Napoleon I, at the present location as the first metal bridge in Paris. Listed as a National Historic Monument on March 17, 1975, the Pont des Arts is also part of the World Heritage Site "Banks of the Seine" in Paris, recognized by UNESCO in 1991.

The bridge has been known for those love locks attached to the railing since 2008. Couples engrave their names on the padlocks and throw the keys into the Seine river after locking them in place as a gesture of committed love. However, as the number of locks became overwhelming, city officials in Paris started to remove some lock-laden railings and replace them with special glass panels in September, 2014. The Mayor's Office in Paris launched a #lovewithoutlocks campaign to encourage people to take "selfies" instead of leaving love locks.

Arcos da Lapa, Rio de Janeiro, Brazil

Postcard BR-263063 from Brazil show the Carioca Aqueduct in Rio de Janeiro, Brazil. Built in the middle of the 18th century in the Lapa neighborhood to transport fresh water from the Carioca River to the city, with an elegant style of colonial architecture and engineering.

The aqueduct was decommissioned at the end of the 19th century, as new alternatives to supply water to Rio de Janeiro were developed. The aqueduct has served as a bridge for the Santa Teresa Tramway since 1896, connecting the city center to the Santa Teresa neighborhood uphill. Originally inspired by the tramway system in Lisbon, Portugal, the yellow tram, as seen on top of the aqueduct, was well-used by residents and tourists alike until an accident killed six people on August 27, 2011. After making design changes to improve safety, it was scheduled to open before the 2014 FIFA World Cup. However, the construction was delayed.

Rio de Janeiro is also home to the Maracanã Stadium (the Estádio do Maracanã), an official football venue with 78,838 seats for the 2014 FIFA World Cup. It hosted a Group F game where Argentina won over Bosnia and Herzegovina 2:1 on June 15, 2014; and a Group B game where Spain lost to Chile 0:2 on June 18, 2014. Belgium defeated Russia 1:0 in a Group H match here on June 22, 2014. Ecuador will play against France in a Group E match on June 28, 2014.

Nizhny Novgorod

Postcard RU-2493226 from Russia shows a magnificent cityscape of Nizhny Novgorod. Also known as Nizhny for short, it is the fifth largest city in Russia with a population of more than 1.3 millions as of 2003. From 1932 to 1990, the city was known as Gorky (高尔基城), named after the famous writer Maxim Gorky who was born there.

As the administrative center of Nizhny Novgorod Oblast, the city is an important economic, transportation and cultural center for the vast Volga-Vyatka economic region in Russia.

Wuzhen, Zhejiang, China

Postcard CN-1163302 from China shows a winter scene at Wuzhen (乌镇), a historic scenic town, in Tongxiang, northern Zhejiang Province, China. It is only lies 68 km south of Tongli, Wujiang county, Jiangsu Province, another historic scenic town that we featured before. Within the proximity of triangle formed by three major cities: Hangzhou (80 km), Suzhou (80 km) and Shanghai (140 km), Wuzhen is a small town that covers an area of 71.19 sq km or 27.49 sq mi, with a total population of 60,000, of which 12,000 permanent residents.

Wuzhen is noted for its historic buildings, stone bridges, stone pathways and delicate wood carvings, mostly from Qing Dynasty (1644 - 1912).

William J. Clinton Presidential Center, Little Rock, Arkansas

Traveling Postcard US-2452513 to Ukraine shows the William J. Clinton Presidential Center and Park in Little Rock, Arkansas, which  includes the Clinton Presidential Library, the offices of the Clinton Foundation, and the University of Arkansas Clinton School of Public Service.

It is located on a 69,000-square-meter or 17-acre land by the Arkansas River and Interstate 30. The main building extends towards the Arkansas River, exemplifying Clinton's campaign promise of "building a bridge to the 21st century." The Clinton Presidential Center was dedicated nine years ago on November 18, 2004. The 1899 Rock Island Railroad Bridge across the Arkansas River, shown on the left of the postcard, was originally leading to Choctaw Station. It has been converted into a pedestrian bridge connecting to North Little Rock and renamed as the Clinton Park Bridge. The dedication ceremony was held on September 30, 2011, and the bridge was opened to the public on October 2, 2011.

The photo on the postcard was taken on April 10, 2006 When I was driving cross-country from West Palm Beach to Las Vegas. The postcard, mailed along with more than a dozen other cards including some private swaps, has traveled more than 30 days. All those cards mailed on that day appear lost in the mail, since none of the cards was received. I am in the process of  re-sending the replacement. So far, one replacement card was received. Unfortunately, some of those postcards are unique and do not have duplicates.

San Francisco - Oakland Bay Bridge

Postcard US-2219312 to Germany shows a fire boat in front of the San Francisco - Oakland Bay Bridge. it opened for traffic today 77 years ago on November 12, 1936, six months before the Golden Gate Bridge opened. The bridge consists of two sections that connect Yerba Buena Island to each shore. The postcard shows the western section between Yerba Buena on the left and downtown San Francisco on the right. The photo on the card was taken on June 25, 2012.

First Bridge of the Yangtze, Wuhan, China

Postcard US-2293208 to Belarus shows the Wuhan Yangtze Great Bridge ( 武汉长江大桥) in Wuhan, Hubei Province, China with a photo taken on October 1, 2007. The double-deck road and rail bridge was the first bridge across the Yangtze River, the longest river in Asia and the third-longest in the world. It opened to public traffic fifty six years ago on October 15, 1957.

The Wuhan metropolis is an amalgamation of three cities located at the confluence of the Yangtze River and one of its branches: the Han River: Wuchang is located on the southern bank of the Yangtze; Hanyang is on the northern bank of the Yangtze and the west bank of the Han; and Hankou sits on the northern bank of the Yangtze and the eastern bank of the Han. Wuhan lies in the heart of Central China and has been a transportation hub between Beijing, the political and culture center in the north and the trading ports of Guangzhou and Hong Kong in the south. The Beijing-Wuhan railway line went into full service in 1906, followed in 1936 by the Wuhan-Guangzhou railway line. Before the bridge was built, train cars travelling between northern and southern China had to be ferried on barges over the Yangtze River, a laborious and time-consuming practice. Plans for the bridge's construction were first made in 1910; and four exploratory surveys were made between 1913 and 1948 for site selection. However, the construction did not start until 1955 due to economic constrains and the combination of World War II and the Chinese Civil War. The construction lasted for two years and was assisted by a 28-person delegation of engineers from the then Soviet Union.

The bridge extends 1.6 kilometers or 1 mile from Turtle Hill in Hanyang, on the northern bank of the Yangtze River, to Snake Hill in Wuchang, on the southern bank of the Yangtze River. The upper level of the bridge has four lanes for two-way automobile traffic while the lower level is a double-track railway on the Beijing-Guangzhou railway line.

Since then, there have been 60 bridges and 3 tunnels built by September 2013 over the 2,884 km or1,792 m main stretch of the Yangtze River, representing a broad array of bridge designs and significant achievements in modern bridge design and engineering.
