While the Government unveiled a new Thameslink train, which will run on the line from 2016 yesterday, tongues were set wagging when it was noticed Harpenden was spelled incorrectly.

During the unveiling of the mock-up of the new state-of-the-art electric Class 700 train, which is to offer more frequent services to St Albans, it appeared Harpenden had been spelled ‘Harpenthen’ on the train map.

The typo could not be changed in time for the grand unveiling at the Excel Centre.

Roger Perkins for First Capital Connect said: "This mock-up of the exciting new Thameslink train was shipped over from Germany where it was created.

"The passenger information screen is just a mock-up of the real thing and its manufacturers were unable to correct the typo in time for the grand unveiling.

The Government said its £6.5 billion Thameslink programme would provide more frequent services from St Albans and 30 per cent more seats because of a 50 per cent increase in carriages.
