It comes after SVR announced on Wednesday it had made the decision to return to diesel-hauled services after a spate of lineside fires.
The fires were started by sparks or cinders from one of SVR's steam locomotives, and Shropshire Fire Service attended and successfully extinguished them.
Steve Wainwright, Severn Valley Railway's head of operations said: “During hot, dry weather, we have to be constantly alert to the risks of lineside fires.
“We have already switched to heritage diesel-only services twice this season; first in July and then earlier this month."
But the railway announced today, that steam services are to resume this Saturday and Sunday for the Purple Weekend, with the No. 70 running on both days.
GREAT NEWS! 🚂 Steam is back this Saturday and Sunday for our PURPLE Weekend with No.70 running on both days 💜 Tickets: https://t.co/nazn4Sj8fC— Severn Valley Railway (@svrofficialsite) September 2, 2022
