An engineering train in the week is a little unusual

with most running at weekends in association with various Sunday possessions and work. I was intrigued to see this 6Y72 working on RTT wondering what it was and if it would actually work. After an hour or so I gave up thoughts of seeing it as it had not left. However, during my walk, I noticed that it had departed from London and was making its sedate way up the WCML. Here it is seen passing Victoria bridge over two hours late with 66560 leading as the 07.30 Blackhorse Road (Walthamstow) to Crewe Basford Hall.
