train to AC world still on two wires
In 2003, Russian Railways signed a contract with Kolomna Locomotive Works, one of the oldest manufacturers of locomotives and diesel engines in Russia (Kolomna Kuibyshev Diesel Locomotive Plant) to create a new six-axle passenger DC electric locomotive with technical characteristics similar to ChS2T DC electric locomotives that had being built for USSR in Czechoslavakia. TEP70BS (ТЭП70БС), modernized version of Soviet TEP70 diesel passenger locomotive just developed by Kolomna Locomotive Works was chosen as the basis for the mechanical design. Electrical equipment was to be supplied by Novocherkassk Electric Locomotive Plant (NEVZ) that already developed and producing EP1 AC electric passenger locomotive. Design was completed to 2005 simultaneously with the completion of certification of the TEP70BS. The bogie construction of the locomotive is similar to diesel counterpart in general but the fabrication process is different (for diesel locomotive is used welded but for electric - massive casted details), both have traditional Alstom design of primary suspension with diagonal link arms and coiled springs and secondary Flexicoil suspension by 4 pairs of coiled springs and in addition, the bogie of EP2K is connected to frame a the pair of massive traction rods. Collectror traction motors are used - ED153U1 manufactured by Elektrotyazhmash plant or DTC-800KSU1 manufactured by Smelyansky Electromechanical Plant, both motors 800 kW at 945 rpm. Locomotive have dynamic brake. From 2006 to present time (2023) were produced 473 locomotives.
Train #227A St Petersburg to Novorossiysk made a stop at Bologoye station of Tver region. The main route of October Railway (St Petersburg to Moscow).
