90021 heads up the "Pretendalino" Mk3 set working the 13.30 Euston - Preston on Saturday.
The loco-hauled set ran back as 1T95 16.30 to Euston on Sunday. The relief services were added following the grounding of all flights over Europe due to the volcanic ash cloud from an Icelandic volcano.
The usual Friday 1P05 was handled by a Pendolino set and extended to Glasgow, with the class 90 working an extra Euston - Birmingham.
