Firstly, can we just correct something - it's GARRATT not Garrett or Garret (which is a make of steam roller I believe).
I note the grumbles about the non heritage nature of the NGG16s, well if you want to see heritage trains on the new WHR then come along to some of the special events like superpwower in sept (the same is true of seeing the pickering carriages on the W+L - only at special events!). In previous years we have had the real and replica summer cars 23/24, bowsiders, bugs and iron sided bogies all of which were used on the WHR, with Prince, Palmerston, Merddin, Taliesin etc. Russell came in 2003 as well, but only got to Waunfawr back then, I dio hope she (he?) graces the full line asap.
and hopefully soon Welsh Pony too. oh and this year at superpower 2010 you'll see some L+B in new build Lyd too.
as for heritage on the line, there is:
Dinas station Building.
Dinas Goods Shed.
The majority of the original NWNG road-over bridges.
The PB&SSR bridges.
Two of the three NWNG river bridges.
Beddgelert Water tower, inspection pit and lamp room base. tank and lamp room to be erected soon.
The weigh houses at Glanrafon and Beddgelert Sidings (base and weigh pit).
The water tower at Portmadoc New (1923) station.
Most of the culverts, (many attractively rebuilt).
Underpasses at Bod Aden and Tan yr Alt
Bont y Cyt - the Croesor tramway bridge over the Cyt in Porthmadog.
Waunfawr station building (to be re- erected when funds allow)
Cambrian Crossing Signal Box, plus associated wooden gates and fencing.
Tryfan Junction station building.
Pont Croesor Waiting Shelter recently erected in style of Ynysfor
A water tank to go atop the preserved water tower at Beddgelert.
and don't forget that in places like Beddgelert a replica of the crinkly tin waiting room would be impossible under current national park planning rules.
oh and how many other heritage railways have been able to recreate the past when it has frankly almost been obliterated. Think of winchcombe on the gwsr - it looks fab now, but that station building aint original! and it's taken them a long while to do it, years since it opened. give the whr project some time too!
