The Sign
The sign depicts a Great Eastern Railway steam train passing over the level crossing on the A12, the Ipswich to Lowest railway line, which passes through the southernmost part of parish. The sign is located in the village centre close to Priory Lane. The same roundel can also be found above the entrances to the new village hall.
