Thank you all for info.[:)] To Lupo's suggestion of elaboration on the layout... all three engines run at rather diffent speeds [:(] (Atlas S-4, Athern GP-40-2, and and some Yugoslavian U-B series which has a 3-pole and no flywheels [may be inserting a 5-pole, can flys be added?]) on a DC (MRC powered) layout. The problem that i was forseeing with just coupling together engines is that the engine closest to the power source would have the most power and by linking all three would equal out the difference. Is this realy a consern? I understand that grade is a bit steep [:I]- but i wanted four inches of altitude between the upper and lower layers, as the under-trussing of the bridge will take some significant portion of that. I guess six feet isnt enought run for that rise. I suppose thats what i get for modifying Atlas's Granite Gorge & Northern - HO-28 [:p](it was designed to be three inches of el - then i modified and bought Woodland Senics foam system-but ill save that for another thread[:D]). Do larger engines (SD's, E-series...) have more pullbar (as models) than smaller ones as they do (on a comparitive basis) in prototype? <br /> <br />As for the Mogul- thanks for the tips-im glad to know thats a common issue[:)]. Ill guess she'll have to wait until I expand my layout[;)] (which will be mostly level) to run her optimally. <br /> <br />And as for the FL-9 (the GM was a typo, sorry), does anyone know of a manufacturer who makes these[?]
