Choosing the southern approach from Cambourne to Cambridge Central has committed Cambridge Transport Planning to sub-optimal solutions for the foreseeable future

All new east-west rail traffic is directed through the most heavily congested part of the railway near Cambridge: Shepreth Junction

All new east-west rail traffic MUST pass through Cambridge Central

Freight traffic could be seen to be a substantial part of the case for EWR as rail freight carbon emissions are only 25% of the equivalent road transport (trucks). 

All new east-west rail freight traffic MUST pass through Cambridge Central

The expected volume of freight from the Port of Felixstowe to the Midlands via this route starts around 20 trains per day (24 hour period), rising to 50 or potentially more

Each train would be made up of around 60 containers

No stations are planned between North Cambourne and Cambridge South.
