Another article from British Railways Western Region - Civil Engineering Department Bulletin - July 1961 What is interesting here is that these new main-line fast crossovers are in bullhead rail, as late as 1961. That's only about 10 years before the introduction of the 1432mm vertical flat-bottom designs. So given a typical life, these crossovers missed out the inclined flat-bottom era entirely. The picture shows the GWR-style switch-diamonds (movable elbows) with a backing support rail behind the switch rails. I have never seen these modelled. (lathes means laths; a diplory is a small 4-wheel bogie) 2_091503_130000000.jpg 2_091503_140000001.jpg 2_091503_140000002.jpg Martin. |
