The 06:34 from Chippenham to Westbury, Salisbury and Southampton last Tuesday morning.

2 passengers left the train at this early hour, and five joined.

I expect the service would be more popular if it provided a reasonable commuter service for a day's work in Trowbridge (where the county is based) or Salisbury.   However, the only train back at the end of the day doesn't reach Chippenham until 8 p.m. which is a crazy length for a day.
