On 15 October 2013, one of the vehicles reached a speed of 201 km/h on theMoscow–Saint Petersburg route, making it the fastest diesel rail vehicle of Polish production.
In 2001, Pesa began producing brand-new rail vehicles. The first was the214M, a standard-gauge diesel railcar intended for the Polish market.[5] In 2004, Pesa started fulfilling orders for broad-gauge rail vehicles. The initial orders were forUkrainian Railways, including the610M inspection railcar designed for the General Director of Ukrainian Railways and the620M units intended for regular passenger service.[6]
On 12 October 2011, during the 9thTrako trade fair [pl] inGdańsk, representatives from Pesa andRussian Railways signed an agreement[7] for the production and delivery of two inspection vehicles, with an option for additional orders.[3] The agreement stipulated that the trains would enter service before the2014 Winter Olympics inSochi.[8]
By the end of June 2013, the first inspection railcar, 611M-001, was completed and began test runs on theBydgoszcz–Inowrocław route in early July. In the second half of July, the vehicle was transported to Russia, where testing commenced on 29 July 2013[9] at the Research and Development Institute of Railway Transport's test track inShcherbinka.[10]
By early August 2013, the second railcar, 611M-002, was completed.[9] On 15 October 2013, it reached a speed of 201 km/h on the Moscow–Saint Petersburg route, setting a record for the fastest diesel rail vehicle of Polish production.[10]
The 611M railcar is an inspection vehicle designed for railways with a track gauge of 1,520 mm, building upon the610M railcar model used byUkrainian Railways.[3]
This railcar features two poweredbogies and driver's cabins at both ends, designed for single-operator control with additional seating for an assistant driver and an inspector.[3][4]
On both sides of the vehicle, there are electrically operated single-leaf sliding doors. Automatically extending steps allow for boarding and alighting from platforms of varying heights. The vehicle is air-conditioned and equipped with double-glazed windows that provide high thermal and acoustic insulation, allowing for operation in temperatures ranging from -40°C to +40°C.[4][7]
The interior of the vehicle is divided into several sections: a conference room with multimedia equipment, a work area, a sleeping section, and a fully equipped kitchen for meal preparation. The railcar also includes a shower cabin and a closed-system toilet.[4]
The vehicle is equipped with communication systems that support various standards, including satellite communication, railway telephone (VHF 160 MHz,medium wave 2 MHz,GSM-R,TETRA), and mobile telephony (GSM/GPRS/EDGE/UMTS/LTE). Additionally, the vehicle is equipped with digital and industrial television systems.[7]
