These styles of coach are classified by Lewis as LA4TN and LA7TN.
There was only 1 LA4TN design and no LA7TN coaches built. Built as Broad Gauge composites, just after being converted to standard gauge coaches they were given slip gear. When the slip gear
was removed they were converted to 3 compartment brake thirds, diagram T30. |
