I am currently building a number of Loco's in 7mm, most advanced is the DJH Kit K311 twin tender Flying Scotsman A3 but I also have Mallard A4 and a Class 37 and Class 40 to work on.
I don't have a layout, merely a test track to check the DCC is all working, It's most about the modelling for me.
I've worked in the Rail industry nearly 30 years now so do have access to some inside knowledge but mostly relating to infrastructure not rolling stock.
Anyway, I like to learn and have trolled the forum scouring information for a while, I thought it was time I posted and said hello.
Cheers
Stuart
