After our 2007 visit I purchased a DVD which has both the up and down trips from the front of the train. Then I purchased the "2007 Year in the Life" DVD of the Ffestiniog, and it has at the back a greatly compressed version of the up trip in 3 minutes.
I actually bought the 2007 Year in the Life hoping I might catch a glimpse of us American visitors during their 175th Anniversary Celebration - and I did! Actually the picture was from Saturday, when my father-in-law and I were taking pictures at Harbour Station. All they catch are our backsides as we watch the train leave.
