Below is a photo that was posted here on the forum a couple of weeks ago. It was taken by my good friend Alan Arnold, (leavingtracks). I have had several folks ask about the roundhouse, the smoke stacks and also the work platforms that are in this photo.
The roundhouse is the 5 stall kit from Dennis Brennan. The kit is fabulous, and I cannot say enough good things about his details and his instructions that go along with this kit.
The smoke stacks and the work platforms are from Dave at Crescent Locomotive Works. Dave does great work, his details are next to none and I would highly recommend him to anyone that wants to enhance their layout with his structures, details, etc.
Thanks for all your questions and good words about my layout.
