TASHKENT LOCOMOTIVE DEPOT
This depot employs more than 2,000 people, about ten percent ofwhom are women employed as engineers, technicians, medical and office staff.
At the depot, diesel locomotives and diesel trains are serviced after 500-550 km of running and receive routine examinations every ten days, minor maintenance every three months and major maintenance after 100,000-110,000 km. Servicing, routine inspection and minor maintenance work goes on around the clock, while the major maintenance and reconditioning shops work two shifts a day.
The depot was formerly used for servicing and maintaining steam locomotives and consists of several workshops providing facilities for servicing and maintenance. The facilities include a general machine tooshop, bogie overhaul, parts cleaning systems, air brake equipment over¬haul, diesel fuel injection equipment overhaul, speed recorder and relay laboratory, parts reclamation shop, and a chemical laboratory with spectroscopefor checking engine lubricating oil.
The parts reclamation shop has equipment for restoring the tin layer on pistons by gas metallization spraying, vibratory arc welding for building up worn steel components such as brake pins and cardan shaft crosses.
During the vibratory arc welding process the work piece is rotated slowly in the chuck or centres of a modified centre lathe driven by an electric motor through an automotive gearbox for slow speed rotation of the work piece. Welded metal is added by submerged arc welding with the electrode wire oscillated over a wide arc during depositing. This is evidentlydone to minimize heating of the stock metal to avoid con-lamination of the weld deposit, thus enabling a more wear resistant surface to be obtained at locations where wear occurs.
