Tehran Metro!

 One of the most Interesting?

There are many great sites to see, if one ever gets to visit Iran, ancient, historical, but the Metro system in the capital is a joy to see and travel on!

Most of the line dates from the end of the Shah in 1979 and was encouraged by the Soviet Union, but Iran has gone on to do their own work and improved the lines into the city with connection to mainline rail?

One does not think that the recent bombings by both the U.S. and Israel targeted any of the structure and that they system is providing air raid cover for civilians!

Most of the stock is modern, compared to other underground systems around the world and they are well maintained and safe, signaling has been improved over the years and comfort designed for large numbers of passengers?

Fire Engines. Part-Three.

Aviation and at Sea.

Every airport across the world has employed specialist fire engines to deal with burning aviation fuel. We generally see this as foam being sprayed from powerful jets, it from years of gathered experience that this method has become a standard. 

Meanwhile fires at sea are extremely dangerous and can be fatal on most types of shipping, if they are not brought under control very quickly. It is the good old faithful Tugboat that has become the mainstay of the sea fire man. These vessels handle much more than towing and assisting shipping, they are fitted with extremely powerful jets and carry large tanks of sea water, than can be continually refilled.

Both in aviation and sea fire, much was learned from the Battle of Britain and the bombing by Nazi-Germany's Luftwaffe of the Port of London docks during World-War-II (1939-45). Tugboat on the river Thames were the most vital piece of sophisticated equipment at the time in fire fighting.
