I was just wondering how high our railroad modelers were making their trestles. I would love to have something like John Allen's but I inherited a train table with a gorge already in the plan. I have been playing around with raising one track above the table which can accomodate a height of 7 1/2 inches on one end of the gorge and 8 1/2 inches on the other end of the gorge. I would love to heard some conversation in regard to the height of your trestles and any other tidbits of information. I just think mine should be higher.
