At present there is a train every two hours between Ipswich and Peterborough stopping at Stowmarket, Bury St Edmunds, Ely and March but these services have become increasingly popular over recent years.
Peterborough is the major junction on the East Coast Main Line and is served by trains heading to and from Scotland, the North East and Edinburgh.
There are also cross-country services from there to Birmingham, Leicester, Manchester, Liverpool and Nottingham.
In recent years there have been calls for the number of trains to be increased as those already running are becoming increasing full but this has always seen as being an issue for the next franchise operator.
However there was widespread surprise when the basic requirements of the new franchise were published last month and there was no mention of the hourly service.
It is important that it is included in the franchise agreement because that will ensure that there are enough trains to operate it there is a national shortage of diesel units which makes it difficult for operators to expand services with government agreement.
Ipswich MP Ben Gummer has asked Rail Minister Claire Perry to ensure an hourly service is written into the franchise: That is very important. We got most of what we wanted from the franchise but not this, but we arent giving up.
I think the government gets the point we are making and I am hopeful it will ultimately be included in the franchise.
Bury St Edmunds MP Jo Churchill has also been lobbying for its inclusion, and hoped that their efforts would be successful.
She said: To the government this might look like a small point, but for those of us in Suffolk, and especially those who use Bury St Edmunds or Stowmarket stations it is a very important issue.
I think we have got the point across and I really hope an hourly service is included when the final route specification is drawn up.
There was widespread surprise within the industry when the hourly service was not included in the original franchise specification especially when the re-introduction of through trains from Lowestoft to London along the East Suffolk Line were included.
These would cause serious congestion on the main lines into London they could only be three carriages long when all the other trains using Liverpool Street are eight to 12 carriages.
And they would introduce diesel engines with all the fumes they create in an enclosed train-shed to an all-electric environment at the London terminus.
final decision on whether to include an hourly cross-country service should become clear early next year. The franchise is due to be awarded during the early summer and the new operator is due to take over in October 2016.
