Hi Al.
Barlow near Selby was on the Selby to Goole line which as you say closed in 1964, the section to Barlow remained open as it served the railway tip which i believe dates back to LNER days, asbestos was found there in 1983 and it was covered in tons of soil. It is now a nature reserve
Drax Power Station uses part the line east of Barlow where a connection was made to the old Hull and Barnsley line.
