Rail passengers have experienced some delays on the Welshpool line over the past 36 hours due to a fault.
Arriva Trains Wales said the problem with line-side equipment was reported early yesterday morning (Monday) and has resulted in trains arriving late.
A spokesman said: “Owing to a problem with line-side equipment between Shrewsbury and Welshpool, train services through these stations may be subject to disruption on all routes at short notice.”
Engineers have worked to correct the fault in a bid to return trains to normal service.
