commerical and industrial railway systems

[AIM]

For anyone interested in Railway history? PICOW and COSS mentioned in previous post. PICOW [Person In Charge of Work] was replaced by COSS [Controller of Site Safety] following Rule Book Change GO/RT 3000 in 1998 when Network Rail [Railtrack as it was then] made everything colorful and user friendly.

I worked on the Railway for 16 years - nearly over it now!
