I would love to see the LTSR 79 class in 00 gauge form because it's a beautiful locomotive and my great uncle used to drive them from Fenchurch street to Southend. Here's some info on the locomotive from Wikipedia: 'The London, Tilbury and Southend Railway (LTSR) 79 Class is a class of 4-4-2T suburban tank engines. They were designed by Thomas Whitelegg, as a development of the earlier 37 Class. The four locomotives ordered by the LTSR were numbered 79–82 and were named after places in Essex, near the LTSR route. After absorption by the Midland Railway in 1912, they were renumbered 2176–2179 and their names were removed. The Midland gave them the power classification 3P, and later continued construction; an order for 10 locomotives was delivered in 1923, just after grouping.' There is a preserved example at the bressingham steam museum of the locomotive my Great uncle used to drive. Photos can be found online of this particular example.
