During WW2 he UK borrowed from the US. After WW2 hey wanted their $$$ back. So cash was sucked out of the UK, But Germany was given Marshall Aid to rebuild. We didn't stop paying the US back for WW2 debt till the 60's.I think you misunderstand the nature of business direction.
A board of directors has to be as objective as possible in its decisions, it does not matter if one 'favours' a course of action or not. The decision made depends on the careful weighing up of all the factors involved. For those items that cannot be precisely quantified an allowance has to be made under the heading of 'risk'.
As you say, it is irrelevant if he was 'in favour' of the generic concept of 'electrification' or not. If a case could be made for a change which would improve the railways' finances then he would support it whether it was the development of the Liner Train or Merry-Go-Round freight services or the electrification of the two passenger routes under discussion.
Regarding the extension of electrification in Europe in the 1950s and 1960s compared to the UK in terms of percentage of the network covered another important, probably more important, statistic to be considered is the percentage of traffic carried by the electrified network. Using this parameter the UK is not so far out of line with other countries due to the predominance of traffic around London, the bulk of which is electrically hauled. Only Paris and Madrid have such a unique centralised position in the rest of Europe.
In any event differing political, economic, demographic, legal and financial frameworks play a significant rôle in such decisions. One has to be very careful to make a like-for-like comparison. For example in my post #92 above I showed how the post-war German experience was very different to that of the UK. Apart from that Germany was experiencing the "Wirtschaftswunder", the rapid growth in its economy from the nadir at the end of the War when, following Ludwig Erhard's reforms of 1948, its Gross Domestic Product (GDP) rose by 8% per year from 1951 to 1961. This was double the rate for Britain and the United States and nearly double that of France.
It was not surprising that the country could afford to electrify its railways.
So much of industry and infrastructure was in a poor state, and struggling to compete.
So money for UK electrification between 1945 and the mid 60's just wasn't there.
