Single Line bronze Key Token CAWBURN JCN - CARMONDEAN JCN No 12, 'C' Configuration. Ex Edinburgh - Bathgate line that was reintroduced in in 1986. The interlocking at Newbridge was delayed and as a consequence, two temporary signal boxes were created at Cawburn Jcn and Carmondean Jcn. In use on this section from 16 Mar 1986 until 4th May 1986. The temporary boxes were then removed following the commissioning of the new interlocking at Newbridge which was controlled from Edinburgh SC.
