Sprayed 'Limpet' Asbestos - the ideal insulation for railway rolling stock
This blue asbestos material supplied by J.W. Roberts really was a wonder material when you consider the benefits that it offered. The 1958 advert listed: high thermal efficiency; reduction in sound level; elimination of drumming; prevention of condensation and corrosion; and fire protection. Sadly, the negatives - unknown back then - known greatly outweighed those benefits and the material became a great burden on the railway and in preservation and caused many deaths. Using a steam locomotive in an illustration this late was unusual, especially when the text does not mention steam, just diesel, diesel electric and electric locomotives.
