Chama Enginehouse Plans

I am looking for plans for the Chama enginehouse. I am building an enginehouse in G-Scale (call it what you will 1:20.3 or 1:22.5) using Piko buildings as the basis. If someone would be willing to communicate with me periodically as I undertake the project I would appreciate it. I have a bunch of questions on floor details now and I am sure I'll have more in the weeks to come. Feel free to use my e-mail or e-mail me a phone number (I'll respond likewise) if we could talk now and then via landline. Plans would be a big help to get me going. Thanks for any help in advance!
