In 2002 Greenham Common Trust introduced a shuttle bus service to and from Newbury town centre and New Greenham Park, providing free transport for everyone visiting the business park. The shuttle bus service forms part of the Trust's Green Transport plan that was published in 2000.

The Trust's shuttle bus allows anyone travelling to and from New Greenham Park to make their journeys absolutely free.

The new free service (routes numbered 3A, 3B and 3C) runs in conjunction with the fare paying 32 and 32A services from Newbury to Basingstoke, which also stop at bus stops on New Greenham Park.

Operated by Newbury Buses, the service will also be available for the general public to use for paid trips around the route.

Greenham Common Trust monitors the bus service and, as a result, has amended the original route to enable as many workers at New Greenham Park to use the service as possible.

Here are the bus stops within the 150 acres of New Greenham Park, numbered to show the order in which the bus visits them, making the service accessible to outlying areas of the park.
