As well as the German epoch table there are other older than Bachmanns version of era/period table that you may care to consider;
DEMU - eras
-----------
1 - Pre 1923 Pre-Grouping Era
2 - 1923-1948 Grouping Era
3 - 1948-1955 Early BR Era
4 - 1955-1968 Transition Era
5 - 1968-1985 Corporate Era
6 - 1985-1994 Sectorisation Era
7 - 1994 onward Privatisation Era
BRM Periods
-----------
1 - Pre 1895 Historic
2 - 1895-1922 Pre-Grouping
3 - 1923-1947 Big four
4 - 1948-1968 British Railways
5 - 1968-1994 Modern Image
6 - 1994 onward Privatisation
But why do people have to undermine and criticise such ideas. Obviously there's lots of over-lap depending on what people choose to remember and/or set the periods by so it's easy to rubbish them by simply selecting another criteria to throw in the arguement pot. No year is going to be the drop dead end of all possible criteria and the shot gun start of everything thereafter. Some things take a while to take off or get established. So remember it's only a guide and is meant to be helpful to those not in the know about everything - not a finite diary on everything concerning the railways.
Appreciate them for what they are - rather than despise them for something they're not.
