A minute’s silence will be held across Britain to mark one week since the Stonehaven derailment on Wednesday.
At 09.43, stations across Scotland will fall silent as a mark of respect, beginning at the time the incident was first reported.
Other stations in Britain will also observe the silence, including those of Abellio-owned operators and Network Rail managed stations.
Alex Hynes, Scotland’s Railway managing director, said: “Scotland’s Railway, and the railway across much of Britain, will fall silent on Wednesday to mark the passing of Brett, Donald, and Christopher.
“Our hearts remain broken and will do for a long time. We hope that by coming together as a railway family, along with the local community and people across the country, we can support one another through this horrendous time.
“The strength of support and offers of help from railway colleagues across the rest of Britain has been a real source of comfort.”
Train driver Brett McCullough, 45, conductor Donald Dinnie, 58, and passenger Christopher Stuchbury, 62, all died in the tragic incident.
ScotRail also has plans for further tributes to be held over the coming weeks and months.
Conservative MP for West Aberdeenshire and Kincardine, Andrew Bowie, welcomed the one minute silence on Wednesday.
He said: “Wednesday’s tragedy was a major blow for the north-east and its impact will persist for a long time to come.
“Having spoken to members of the railway community, who very much consider themselves a family, a great sadness is being felt across the whole of Britain.
“I appreciate the many expressions of sympathy in all forms so far, and welcome an official moment of memorial this week.”
A three-minute silence is also being held at 7pm tonight for the victims after being organised by Wray Thomson, founder of Man Chat.
A statement on the Facebook event page said: “Following the tragic news unfolding in the north-east from Wednesday morning we ask all residents of the northeast to observe three minutes of silent contemplation for those who tragically lost their lives in the Stonehaven rail accident.
“We wish all those affected well and extend our support if required.”
