Plans to build a steam railway station in the heart of a Gwynedd village have upset local people.
One resident has mocked up a photograph of how he claims the station will look from his garden
Planning permission for the station at Beddgelert dates from 1999, but villagers claim they had no idea the building would be so close to homes.
The Welsh Highland Railway said the location was not up for discussion but they would discuss any concerns with residents.
Snowdonia National Park planners discuss detailed designs on Wednesday.
Alan Tranter's home is the nearest to the proposed new station, which will serve the narrow gauge line from Caernarfon to Porthmadog.
He found out about the development in a letter from the local planning authority.
He says he was horrified to find the building would be just over his garden wall, with the station's toilet facility facing him.
Mr Tranter says he and "99% of the village" assumed the new station would be built on the exact spot of the old building, which was 40ft by 12ft, and further upfield from his house.
"Instead the new building will measure 70ft by 40ft and be much closer to nearby houses," he said.

"This is a picture postcard village and we need permission to change a window in our homes because we are in the national park, I can't believe they will be allowed to build this station here," he added.
Peter Marsden, a director with Welsh Highland Railway Construction Ltd, which is responsible for the work, said: "I understand that some residents are unhappy with the location of the new station.
"The locations is not up for discussion as the position and size of the building was approved in 1999.
"We are now seeking approval for the detailed design of the building," he said.
Villager Daniel Wheatley thinks the development will "spoil the village" and is worried about parking problems.
"We're not certain how they plan to access the site as there is no vehicular access at present," he said.
The rail company has offered to meet residents.
"We are more than happy to discuss any concerns people have with the design in the hope of coming to satisfactory conclusion," said Mr Marsden.
