Next Tuesday (6 September) a Pioneer engine train will be named after the designer of the London MI6 building.
This unprecedented move by a Hull-based train company celebrates the architect's contribution to the regeneration of the northern city.
Farrell has been especially praised by Hull Trains for his iconic 'submarium', 'The Deep', as well as his masterplan for the River Hull Corridor.
Three other trains will be named by the rail company after individuals who have raised the profile of Hull.
The unveiling ceremony is to take place at King's Cross station in London, shortly before the train leaves the platform at ten minutes past midday.
