I did get a M1B 2-8-4 up it...It wasn't pretty but it was pulling a big tender and two pretty heavy cars... I am thinking if a had a 3 truck shay and 3 skeleton log cars it might go better...I am going to go sleep on it.It is 1:30AM here on the east coast... Thanks for the intput and I love some of the ideas I got on this forum and the replies are lightning fast...Keep em coming and thanks sooooo much... G'Night All
