The class 6 working is an Out of Gauge working hence the X in the headcode. Note also that each wagon has 5 pipes on it rather than the usual three.
35 pipes are being conveyed on 7 wagons as 66102 takes 6X88 across Jamestown Viaduct.
Whilst the train went left at Inverkeithing South Junction and up through Dunfermline, I headed up the motorway to Halbeath and just got to the level crossing in time to catch 66102 passing the site of Halbeath station which closed on 22/9/1930. 14/10/10
