Central discontinued their single Northampton service a day which ran to Nottingham (and other locations) via Birmingham once they gained the Birmingham to Northampton route from sister company Silverlink Trains in 2004/05. Two trains per hour from Birmingham New Street – London Euston via Northampton was replaced by one train per hour to Northampton which connected badly with onward services to London Euston (although a few trains a day did run straight through to / from London as an unofficial joint service). The Northampton service started off as an hourly express service until it was merged with the local service to Coventry adding more journey time.
