The stock is temporarily being stored in the small village while construction takes place on the $15million museum upgrade.

The upgrade, which began in March, will provide better public access for visitors and tourists.

But Buxton resident Kath Albertiri said she was disappointed her village had been turned into a dumping ground for old train carriages.

``It's been there for a couple of months now and they're slowly introducing more and more carriages,'' she said.

``It started off with a couple of big old rusty carriages and now there are about 18 of them.

``It's across from the park and children are always up there, climbing all over them, especially in the school holidays.

``I'm worried because it's just so dangerous and someone could be seriously hurt.''

NSW Rail Transport Museum boss Richard Mulvaney apologised for the inconvenience to residents.

He said the museum had the lease of the corridor and could store rolling stock on any part of it beyond the active line.

``We've had to relocate some of the rolling stock to Buxton because of the major track-work that's happening as part of the Thirlmere upgrade,'' he said.

``At the moment we're probably at our most restricted stage of the construction, as the new track-work on the southern boundary of the yard still has to be completed.

``At the same time we're relocating rolling stock out of the northern section of the yard to get access for the remedial work of the existing display shed.''

Mrs Albertiri said graffiti was becoming a problem on the carriages. ``It annoys me every time I drive past and it's becoming an embarrassment to say where I live,'' she said.

Mr Mulvaney said the stock had been parked in Buxton longer than intended. ``We understand they've proved a physical barrier for people crossing from one side of the town to the other,'' he said. ``We thank the Buxton community for their understanding.''

He said some rolling stock will be moved to a temporary site at Balmoral and the guards' vans will be moved back to Thirlmere.

``Some of the items are part of a disposal program under RailCorp and the museum was waiting on final confirmation for pick up.''
