There were so many non - PC loco names in the days of steam.
The naming policy of the LNER would not do at all today.
For example the A3 Class included 60108 "Gay Crusader" and 60099 "Call Boy" which nowadays have new connotations, the former could also be subject to religious discrimination.
The preserved A4 60009 "Union of South Africa" has in recent years been subject to criticism.
There was one whole class of locomotives, now sadly extinct, that could have lead to protests by the anti blood sports brigade. I am thinking about the LNER D49/2 Class, the Hunts. Fortunately a D49/1 Shire Class has been preserved: Morayshire is PC.
The LNER also built the D11/2 Class in 1924 and continued the North British Railway tradition of naming locomotives after characters in Sir Walter Scott's novels. They gave us 62686 "The Fiery Cross", which was even then a symbol of racial persecution by the Klu Klux Klan in the Southern States of the USA.
However amongst the North British Railway Class D30 I have found my all time favourite. Above the prejudiced 62441 Black Duncan and 62427 "Dumbiedykes" stand the religious extremes of 62438 "Peter Poundtext" and 62439 "Father Duncan", and then finally, the absolute gem that should send all the ladies into fainting fits: 62440 " Wandering Willie".
Come to think about it, the new Class A1 60163 "Tornado" is not all that PC if you happen to be on the receiving end, especially if you are Argentine, Arab, or a citizen of the Southern States.
Besides all these magnificent precedents set by the NBR and LNER, how can we possibly come up with anything to rival them?
My suggestion of how to raise a real stink: yesterday was the bi-centenary of the battle of Trafalgar. We have a few Jubilees around, lets renumber them 45712 "Victory" and 45682 "Trafalgar", 70013 could become 70014 the "Iron Duke" and Britannia could come undisguised. To give our group of Francophobes a GWR flavour, also disguise a King as 6019 "Henry V", the victor of Agincourt. Then assemble them all at Waterloo Station and name a Eurostar "Lord Nelson" at one end and "Waterloo" at the other. That should do it.
