The deadline for bids to buy the last remaining inland funicular railway in England closes on Friday.
The Bridgnorth Cliff Railway in Shropshire was opened in 1892 and owners Allan and Jean Reynolds have run it for 15 years.
The couple said they were selling it, and the Grade II listed buildings at the top and bottom of the cliff, for between £700,000 and £800,000.
The railway transports people up and down 111ft sandstone cliffs.
Two cars on parallel tracks, connected by steel ropes, counterbalance each other - as one rises to the top station, the other runs to the bottom station between High Town and Low Town.
The cars are now powered by an electric winding engine, but were originally driven by a system of water balance.
Mrs Reynolds, who is retiring with her husband, said at the height of the tourist season the railway makes 200 journeys a day and carries 2,000 people, who pay £1 for a return ticket.
There are thought to be around 15 working seaside funicular railways left in England.
