As an aside, I have just had to travel from Long Buckby, (the fourth visit in eight days), and the machine has been out of service every time...
I happened to be passing through Long Buckby yesterday (by car) so took a look. TVM definitely not working, it looks like a screen problem - although it's completely unreadable I suspect the TVM might actually not be off line.
If it's been out of order for so long why don't LM attach a notice adising passengers what to do or is that too simple?
