How does Wantage Tramway meet the criteria for inclusion On the main List of town tramway systems page the list of criteria for inclusion say that steam tram systems must use a specific type of tram engine completely enclosed with no steam or smoke emissions and no visible machinery more than 10 cm 4 above the track I have seen pictures of the Wantage Tramway and the engine preserved at the Didcot Railway Centre and it appears to be a conventional tank engine Does it not therefore qualify as a light railway under Wikipedia s own definitions
