During the investigation of the fatal accident that occurred at Zhipkhegen station of the Chita Territorial Administration of the Trans-Baikal Railway on November 12, 2025, at 11:26 p.m. Local time, it was determined that one of the causes of the incident was the lack of stable radio communication between the driver and the shunting supervisor. When the shunting supervisor issued the "stop" command twice over his portable radio, the driver of shunting locomotive TEM 18 DM No. 830 did not hear and did not comply. The shunting supervisor stopped the 22-car shunting train by opening the end valve, and was pinned between the tail car and the stop of the dead-end prism, on the non-public loading and unloading track of Burtuy LLC No. 6.

According to the interception report of the communication regulations at Zhipkhegen station (Gradient 12SN (8) communication recorder No. 44360/2365/9977, channel No. 4, shunting radio communication (MRS-VHF), 1st district) dated November 12, 2025. The train dispatcher gives commands to the locomotive driver:

At 11:24:54 p.m., "On the right, on the shoulder, train 830." At 11:25:14 p.m., "Car 830." At 11:25:33 p.m., "Stop, train 830."

At 11:25:43 p.m., "Stop, train 830." At 11:25:59 p.m., "Forward, train 830." At 11:26:07 p.m., "830." The locomotive driver did not acknowledge these commands.
KPD, CLUB-U – the cassette was compared by time, the TCHM confirmed with a whistle (a siren): it's unclear from the listening report how he understood the TCHM compiler's commands and how he rehearsed them.

At 11:25 PM 59 sec – "830 forward" – how many meters and what, half a car, a car? So the driver understood the command: "We're standing still, 830" at 11:25 PM 43 sec!!!

At 11:26 PM 07 sec – "830" – What?

According to the stamp in the TU-152 log, on 12/11/2025, shunting diesel locomotive TEM18DM No. 830 underwent maintenance as part of TO-2. As part of the maintenance, the radio station's operating parameters were to be checked, any discrepancies corrected.
Were there any entries in the TU-152?
and routine maintenance was performed. The stamp contains the entry "Checked and in good working order. ZabTRPU-17," made by the TRPU personnel performing the routine maintenance.
During a commission inspection of the radio communication devices on shunting locomotive TEM18DM No. 830 on November 14, 2025, it was discovered that during the train dispatcher's communications from the scene using a Motorola DR-2400e portable radio,

Is this the same radio station? When and who performed the inspection? What is the condition of the battery? Using a remote manipulator with the driver of TEM18DM diesel locomotive No. 830, the locomotive driver cannot hear the train marshal's commands, though the commands are heard via a Motorola GP-340 portable radio in the locomotive cab.
What is the actual field strength at the locomotive's antenna? What is the interference level? The RCS must have an INP.
During a commission inspection of the radio communication devices on TEM 18 DM locomotive No. 830, measurements were taken of the parameters of the RLSM-10 locomotive radio station No. 02872/06.14. The inspection date at the KRP was January 29, 2024 (the next inspection date was January 29, 2026). The measurements were taken using the STOR-N locomotive radio station testing and measurement device No. 0300040721.
Year of manufacture: 2014.
TELEGRAM of JSC Russian Railways No. 10569/CT dated July 28, 2017, signed by TSG O.V. Chikirkina, regarding amendments to the technical specifications for locomotive radio stations: "The recommended service life of the RLSM-10 is at least 10 years."
PTE PRS No. 761/r
6.2.3 Responsibility for radio station malfunctions due to disassembly, as well as for malfunctions during operation of radio stations whose recommended (assigned) service life has expired (regardless of the radio station's inspection or repair period) or whose maintenance or repair period has expired for the TPS, MVPS, VSMPS, or SSPS on which the locomotive radio station is installed, rests with the owner of the radio station.

Internal radio testing was conducted in the locomotive cab. TEST-1, TEST-2, and STOR-N. TEST-2 does not support TEST-3. The radio is operational, but the receiver sensitivity was 3.2 μV.

Instructions
for updating software for RLSM-10 locomotive (mobile) radio stations
5. Recommended transceiver settings
5.2 Recommended settings for the MPP-150, MPP-160, and MPP-160D modules:
PSH: "-10"
ATTENUATOR: "0"
SNR: "7"
with a standard of no more than 0.5 μV
measurement was performed with the actual set PS level
(does not comply with the radio's operating instructions). Testing is required at the RCS (KRP) control and repair center. To check sensitivity, according to DEKS.464117.001 RE2 RLSM-10
