East Midlands train drivers have been criticised by the operator for being "hell bent on trying to disrupt the Olympics".
The comments from the Managing Director of East Midlands Trains, David Horne, come after the drivers' union ASLEF confirmed that it will take further strike action during the games.
A walk-out is planned for the 6, 7, and 8th August, which is in the middle of the Games when Usain Bolt, the fastest man on earth and one of the most anticipated competitions of London 2012 is taking place.
The strike action is due to a row over pensions, East Midlands Trains have accused ASLEF on going back on a deal brokered in talks last week:
"If ASLEF does not have a change of heart, it will be remembered long after London 2012 as the union who tainted the pride of Britain in disrupting such a once-in-a-lifetime sporting event."
– David Horne, Managing Director of East Midlands Trains
However the union ASLEF said it was deeply saddened that the union finds itself in this position:
"ASLEF is disappointed that recent talks with East Midlands trains did nothing to address major pre-existing concerns ASLEF has in relation to its dispute between EMT and ASLEF members."
"ASLEF is deeply saddened that the union finds itself forced into this position by East Midland at this time."
– ASLEF Spokesperson
East Midlands Trains says it will aim to provide as many seats as possible for people travelling to the Olympic Games.
