In January, Tops Pizza, a 42-store takeaway chain, had its west London warehouse requisitioned because it lies on the route of the new HS2 high speed rail line.
More than six months later, the company has not been paid for its land.
Owners of scores of other properties along the £27.4bn first phase of HS2, which will run from Euston station in London to Birmingham, have had the same experience.
Despite rules stating they should receive 90% of the compulsory purchase price upfront, there have been long delays to payments and some are considering legal action.
