Medway Council has issued a formal notice to contractors over works worth £48million to restore passenger services on the freight-only railway in the Hoo Peninsula for the first time since 1968.

The £63m rail modernization and restoration program is part of a wider £170m investment in the Hoo Peninsula from the Government’s Housing Infrastructure Fund to improve access and neighborhoods .

The rail project will upgrade the existing 19km Grain Branch line, which is a single two-way freight-only line that connects the Isle of Grain to the North Kent line at Hoo Junction. The upgrade will allow residents of the Hoo Peninsula to access the mainline, which runs regularly to London.

The existing line will require upgrades to allow passenger services to operate while maintaining freight services. To do this, new sections of double track will have to be installed to create loops where trains can cross paths. Some bridges on the route will need to be upgraded to accommodate dual carriageway.

Key to work on the line is how the trains will be powered. Battery and hydrogen trains were considered, but were ruled out due to their need for new rolling stock. Instead, it was proposed to extend the existing third railway electrification system on the Grain line.

The work will also include the construction of a new station around the midpoint of this line, south of Sharnal Street.

Wherever possible, materials will be sourced locally and brought to site along the railway line.

The work is divided into three phases.
