Two railway employees were killed after a high-speed train plowed into them following a communication lapse about ongoing track construction, Sixth Tone’s sister publication The Paper reported Sunday.

The accident occurred Friday morning while the two were working on the Tianjin segment of the Beijing-Tianjin rail network, according to the media report. The workers had reportedly missed an update relayed by their superior on social messaging app WeChat regarding the track’s operation time.

The deceased worked under the Beijing Railway Administration, the report said. The accident has been attributed to lax observation of operating procedures and safety systems.

The person in charge of the operation has been removed from his position amid an ongoing investigation, The Paper reported. The high-speed train involved in the accident was not carrying passengers. (Image: VCG)
