I found it by accident and enjoyed it but there was a lot of daft stuff in it. For example, I'm perfectly sure that the control room on the train would have an entry code and not be left open for any Tom, Dick or Harry to waltz in.
Also, despite the repeated instruction from top brass to remove passengers as quickly as humanly possible, the police and train guards didn't seem to have quite understood the memo. In fact why was it taking an interminable age to remove the wheelchair user? Knowing that the train could blow sky high at any moment, surely one of the guards or the police would have physically carried her off the train. Instead the buffet girl was aimlessly sauntering around looking for a suitable ramp. In the end, they left her on the train anyway.
When Jo (was that his name?) our anti hero finally got the end door open, why didn't he tell the boy to run immediately to his mother instead of letting him linger?
