There have been loads of railtours with cryptic names
For example, 'The Lost Sheep' was a Hertfordshire tour run in 2003, which covered many lines along the south coast, including Bopeep Junction near Hastings.
Just after Milton Keynes Central opened in the 1980s a railtour which visited there was called 'The Concrete Cow'.
And how about the 'Coalville Cobbler' railtours which ran to the annual Coalville open days using Mk1 stock from Northampton commuter services, hence 'cobbler'.
Another favourite of mine was 'The Long Thin Drag', a Hastings DEMU farewell railtour which travelled over the Settle & Carlisle line.
