Man charged in Jordan Neely’s subway chokehold death
Daniel Penny turned himself in on May 12 after being charged with second-degree manslaughter in the death of Jordan Neely on a New York subway train.
Experimental studies of the process of initiation and spread of the dangerous fire factors while burning of the tube stock in the tunnel
The present article is concerned with the analysis of the experimental results performed with full-size large-scale prototypes of tube stock in subways in case of the fire in the tunnel. The process of the fire spread in the passenger compartment and along the tube stock is investigated.
The Routes Not Taken: A Trip Through New York City's Unbuilt Subway System
Delves deep into the underbelly of the NYC subway system to reveal the tunnels and stations that might have been. Robert A. Van Wyck, mayor of the greater city of New York, broke ground for the first subway line by City Hall on March 24, 1900. It took four years, six months, and twenty-three days to build the line from City Hall to West 145th Street in Harlem. Things rarely went that quickly ever again. The Routes Not Taken explores the often dramatic stories behind the unbuilt or unfinished subway lines, shedding light on a significant part of New York City's history that has been almost completely ignored until now. Home to one of the world's largest subway systems, New York City made constant efforts to expand its underground labyrinth, efforts that were often met with unexpected obstacles: financial shortfalls, clashing agendas of mayors and borough presidents, battles with local community groups, and much more. After discovering a copy of the 1929 subway expansion map, author Joseph Raskin began his own investigation into the city's underbelly. Using research from libraries, historical societies, and transit agencies throughout the New York metropolitan area, Raskin provides a fascinating history of the Big Apple's unfinished business that until now has been only tantalizing stories retold by public-transit experts. The Routes Not Taken sheds light on the tunnels and stations that were completed for lines that were never fulfilled: the efforts to expand the Hudson tubes into a fullfledged subway; the Flushing line, and why it never made it past Flushing; a platform underneath Brooklyn's Nevins Street station that has remained unused for more than a century; and the 2nd Avenue line long the symbol of dashed dreams deferred countless times since the original plans were presented in 1929. Raskin also reveals the figures and personalities involved, including why Fiorello LaGuardia could not grasp the importance of subway lines and why Robert Moses found them to be old and boring. By focusing on the unbuilt lines, Raskin illustrates how the existing subway system is actually a Herculean feat of countless political compromises. Filled with illustrations of the extravagant expansion plans, The Routes Not Taken provides an enduring contribution to the transportation history of New York City.

Indoor concentrations of radon in Cairo subway
The current study was going to detect radon concentrations in one of Cairo’s subways. The radon gas was detected in certain common positions chosen for thirteen stations. Plastic cans were prepared to hold the CR-39 samples and to be positioned at their destination in the stations. The cans were installed through two periods of one month and two months. Afterwards, the track density of radon gas was calculated for all the collected samples and then the concentration of radon was estimated in the stations. It was found that the average value of Rn concentration in the thirteen stations exceeds the average normal Rn concentration indoors. The measured values are less than the recommended maximum value of 300 Bq m −3 for radiation protection of residents according to ICRP Publ. 126. The indoor average radon concentrations were found less than the action level of 300 Bq m −3 , 100 Bq m −3 , and 148 Bq m −3 as recommended by ICRP, and WHO, respectively.
