The ASTM F1554 specification was introduced in 1994 and covers anchor bolts designed to anchor structural supports to concrete foundations. F1554 anchor bolts can take the form of either headed bolts, straight rods, or bent anchor bolts. The three grades 36, 55, and 105 designate the minimum yield strength (ksi) of the anchor bolt. The bolts can be either cut or roll threaded and a weldable grade 55 can be substituted for grade 36 at the supplier’s option. Color coding on the end – 36 blue, 55 yellow, and 105 red – helps facilitate easy identification in the field. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements. Applications for F1554 anchor bolts include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign structures to name just a few.

    Almost 4 hrs late 12260 Mew Delhi – Sealdah Duronto Express trying to cover up some time under the madly honking 30204 Howrah WAP 7.

    Enjoy the beautiful landscape of Gurpa – Gujhandi ghat section which falls between the two major stations Gaya and Netaji Subhash Chandra Bose Gomoh.

    This video is for all the people who are yet to visit Eastern India, specially for u Mr.Honourable ;-)

    Here is a brief description, history of this ghat:

    The Asansol–Gaya section is a railway line connecting Asansol and Gaya. This 267 kilometres (166 mi) track is part of the Grand Chord and in under the jurisdiction of Eastern Railway and East Central Railway. The section links to South Eastern Railway through Bokaro Steel City and Adra.
    The Bardhaman-Asansol line was first extended to Barakar in 1858 and then in 1894 East Indian Railway Company extended the line to Jharia and Katras, opening up the Jharia Coalfield. Dhanbad emerged as a premier coal loading area. One railway-related source says that the line from Sitarampur to Dhanbad was built in 1880.
    Once the rail link from Howrah to Delhi was completed in 1866, the East Indian Railway was making constant endeavour to reduce the distance of the Howrah-Delhi main line. After several surveys, one in 1888-89 and two more subsequently, a route was determined from Dhanbad to Mughal Sarai via Koderma and Gaya. The major works in this section were a bridge across the Son River at Dehri, and tunnelling and ghat line construction between Gurpa and Gujhandi.
    The 22 kilometres (14 mi) Gujhandi (altitude 370m)-Gurpa (altitude 193 m) section, 10 kilometres (6.2 mi) west of Koderma, is a ghat (mountain/hill slope), with the Koderma Plateau sloping down to the Gaya plain.
    The Grand Chord was opened on 6 December 1906 by Lord Minto, then Viceroy and Governor General of India with a function at Gujahandi. The Viceroy and Lady Minto travelled to Gaya, from where they travelled in a special observation car to Gujhandi. Two special trains, running from Howrah, carried the invitees. The Viceroy screwed on a silver bolt with a silver spanner to formally complete the line.
    A repeat of the historic event was organized by East Central Railway on 6 December 2006, with a special heritage train “Grand Chord ki Rani”, pulled by a 1965 steam engine, carrying the guests from Gaya to Gujhandi.
    Several years before the Grand Chord was built, a connection from the Howrah-Delhi main line to Gaya was developed in 1900 (presumably the Patna-Gaya line) and the South Bihar Railway Company (operated by EIR) had laid a line from Lakhisarai to Gaya in1879.Track doubling of the 130 kilometres (81 mi) long Kiul-Gaya section was announced in the railway budget for 2010-2011.
    Completion of electrification of the 97 kilometres (60 mi) Patna-Gaya rail route before the end of 2003 was announced by the railway minister Nitish Kumar.
    The Bengal Nagpur Railway system was connected to the East Indian Railway Company lines in 1889, thus connecting Asansol to Adra. In 1907 Adra was connected to the Grand Chord at Gomoh.
    In 1902, a branch line of EIR was opened from Sone East Bank (later renamed Son Nagar) to Daltonganj. With the development of South Karanpura Coalfield, the Central India Coalfields Railway opened a line from Gomoh to Barkakana in 1927 and from Barkakana to Daltonganj in 1929. These lines were subsequently taken over by EIR.
    The Howrah-Gaya stretch was electrified by around 1960.
    In 1965, Asansol-Bareilly Passenger was the first long-distance train on Eastern Railway to be hauled by an AC loco.
    Most of the Asansol-Gaya section is classified as ‘A’ class line where trains can run up to 160 km per hour but in certain sections speeds may be limited to 120-130 km per hour. The Howrah Rajdhani (between Howrah and New Delhi) travels at an average speed of 85.8 km per hour and the Sealdah Rajdhani (between Sealdah and New Delhi) travels at an average speed of 84.70 km per hour.
    The Asansol-Gaya line forms part of the golden quadrilateral. The routes connecting the four major metropolises (New Delhi, Mumbai, Chennai and Kolkata), along with their diagonals, known as the golden quadrilateral, are the most important routes in terms of passenger and freight volume. Although they constitute only about 16 per cent of the total route length, they account for about 50 per cent of the total freight and 47 per cent of the total passenger traffic.
