Home made trestle
WIth track increasing I needed to give my trestles a little needed advantage. So I increased the width for flexibility. The tunnel is 4,1/8 inches by 4, 1/8ths. THe home made trestle is 4, 5/8ths high. I copied the trestle height and check out the dimensions from a foam tunnel I have. The rest was cut with a coping saw and wall pappered with my paper O scale buildings cut to fit. I had to hide the widows though.
I made three but I need only one for now.I used quarter inch plywood for the top for strength because the wood boards split along the grain. I painted the seams gray and printed in black and white to match.
On line there are many sites that have printable aides for backdrops etc. I thought of brick but just used what I had. Some I found were pay sites.
I just checked this thread has 600 views!. I don't remember seeing that many.
