The little " 5500 " class tank locomoive is seen here approaching "Old Chapel Viaduct " ,a six span concrete strucure and is heading its train towards Barmouth at what would appear to be low tide judging by the stranded boats !
Passengers looking to their left at this point would have a good view of Barmouth harbour before their train comes off the single line and enters the twin track layout of Barmouth station .
the " 5500 " locomotives , with their larger water tanks , came on to the Cambrian line when it was found that their smaller " 4500 " sisters were restricted to short duties due to their inadequate water capacity and both versions worked local passenger and freight rosters , the freight workings usually being between Portmadoc and Pwllheli .
