Hello 31B and welcome to a great forum.
Are you a member of the local Wisbech & March Bramley Line yet? If no, then why not, because they hope to have the occassional steam loco as a Guest when they restore that link. PM me for details, or simply go to
www.bramleyline.org.uk and take a look, because the TCT/Bramley Boys are working in your area on a Sunday at present and they would welcome you, that's for sure.
