3. 8; Fibonacci sequence - or maybe grahame wanted a different railway-related answer?

You're correct ... I slipped just that one general sequence into the railway-specific ones. But I'm sure that someone will come up with a rail answer to! 6. Fusilier; in numerical order, the name of the next surviving member of the Western Class locomotives.
D1010 Western Campaigner, D1013 Western Ranger, D1015 Western Champion, D1023 Western Fusilier
Yes indeed. I was looking at a warship sequence too, but I don't think enough have been preserved. I wonder why - personally I found them more artistic looking that the westerns. |

I thought there must be SOME link between trains and Fibonacci - and came across the following: https://mast.queensu.ca/~math9-12/manual/TrainsManual.pdfCounting Trains
This is quite an interesting activity. In line with my big theme of par- allel structures, it presents the students with two worlds:
The Fibonacci world. A sequence of integers generated with one of the simplest of all recursive generators: . This is an abstract world which contains many unexpected patterns, some of which we will encounter here.
The trains world. A sequence of integers with a concrete realization (number of trains of a fixed length) giving us a powerful access to the surprising patterns of the Fibonacci world.
In this unit the students are challenged to provide proofs for some of the well-known Fibonacci formulae by invoking properties of the structure of trains. Edit - rewritten part of my post which got lost in submission ... |

4 - Birkenhead (stations on the Wirral served by Northern Rail, but they don't seem to be in the right order?)

Not Birkenhead - you're headed in the right direction, but the answer goes a little further. |

Not Birkenhead - you're headed in the right direction, but the answer goes a little further. Then is it Chester, as the fourth (and last) Merseyrail (Wirral Line) terminus? But I've no idea what the chosen order is about. PS: It's distance from Hamilton Square (or beyond), isn't it? |

It is indeed Chester ... and the order is the typical sequence of departures from Liverpool ... it's not 100% the same all the time, but once the other three have left it's pretty much certain the next one will be to Chester! |

Is this a continuous restriction, or does the 24 hour override apply? |

1: 1994, the fourth derailment at Morpeth, Northumberland - 1992 was a collision between two trains.

2. 10:02 Northbound train departures from Melksham on a weekday (although this doesn’t quite fit as the sequence would be 05:33, 07:20, 07:51, 10:02)
