The text reads '700 miles of Southern Railway will be electrified by spring next year - 3 new new sections open this summer - 3 electric for every steam train now running - total cost £8,000,000'. This is one of a series of adverts promoting the Southern's investment programme under the general theme of progress. The others are Steam, Rolling Stock and The Viaduct. The series was designed in 1925 by T D Kerr. To put the sums involved into perspective, £8 million in 1925 money would be (using the retail price index for conversion) the equivalent of £289 million in 2010. |
