Detailed map of St.Thomas yard   Here we have a highly detailed map of the St.Thomas yards and surrounding area, as of May 1949. The original comes from Bob Bowes and measures about 2 feet by 4 feet. The original scan file was 236megabytes!! This is a too big for normal viewing and would be nearly impossible to work with on most computers.   Due to the large size of the file, I offer two different size files, depending on how big a file you wish to download.    Low resolution St.Thomas yard map - 246kb High resolution St.Thomas yard map - 2.572Mb
