Wagons of the original North Wales Narrow Gauge Railways and Welsh Highland Railway. Many vehicles purchased by the former were taken over by the WHR on its formation.
There is no evidence to support any suggestion that the Welsh Highland in any form has used the double g spelling for waggons
 NWNGR wagons
The NWNGR seems to have had at maximum about 150 assorted wagons but few written records have survived. The Annual Returns start at 114 in 1877, peak at 147 in 1892, declining to 113 in 1921. However Major Spring's report in the same year gives a total of 150. Maybe he counted derelicts which had officially been withdrawn and so were not counted in the official return. Boyd also mentions about 30 wagons owned by the quarries (both open frame and plank types) and if still on the system some of these may have been accidentally included in Spring's totals.
- Slate Wagons (NWNG)
- 2-plank Open Wagons
- Large Open Wagons
- Cleminson Coal Wagon (NWNG)
- Ridge-roofed Covered Wagons (NWNG)
- Tipping Wagons (NWNG)
- Timber Wagons (NWNG)
- Brake vans
Survivors of this stock passed to the WHR in 1923.
 Original WHR wagons
For the opening of the WHR in 1923 no new wagons were provided, but the remains of the NWNG stock were taken over. It appears there was no proper list of the NWNG stock available at this time. Robert Williams of the FR went to Dinas in 1922 to take stock, but as reported in Boyd, he produced a list that totalled 124, and a report adding up to 116. Much of the NWNG stock was then derelict. Some was repaired and repainted but probably not renumbered. None of this stock survived the scrapping of 1941.
FR wagons were used also, particularly in the early years. A Brake Van (No 4) and a Meat Van were converted from Quarrymen's carriages for use on the WHR, but probably remained FR property. These have not survived.
Some ex-WD bogie wagons were acquired and used on the WHR but it is not clear which were WHR and which FR property - see Bogie Wagons.
 New WHR wagons
For the reopening of the WHR from 1997, a new stock of wagons has been acquired, mostly from South Africa. For details see WHR(C) Wagon List.
