great stuff brendan. you were right about a multilevel layout...its the only way to go. have to say that i had hugh doughts about it but am converted. work has finally settled down , in the fact that the main building is closed and all in situ were transferred to community settings just last monday, so with that , overtime etc have gone , and so i finally have the time to start the layout. all stock is stored and nearly all the boards lifted - so heres to the start of something new for me. can i still call you for assistance and advice? seamus
