[quote]QUOTE: Originally posted by mudchicken You are looking at 22-24 ties per rail length and any main line will hold the 24 ties/ rail length typical standards. Along with the beam issue distributing the load footprint, you seem to be ignoring the cyclical issue that accelerates the degradation of the track variables....If you want to throw all those extra ties in there, hope you can come up with the machinery to index and surface that works. IMHO, The "benefit" you keep pushing won't be fiscally justified (ROR for the railroad isn't there for the outlay required). Be heavy and go fast requires a massive maintenance commitment that the operating side has to buy into or the whole thing stumbles a la Powder River. [/quote] There's more to it than just more or less ties per rail length. What about different widths/thicknesses of ties in correspondance with differring rail thicknesses? "X-ing" ties rather than cross ties? Ect.? I still haven't seen any studies to refute the hypothesis, mostly I presume for the simple fact that re-thinking the rail/tie interaction combined with rail wheel interaction hasn't even been broached by the R & D departments (if the Class I's even have their own R & D departments anymore outside the TTC!) If there are any studies out there that have examined relative rail thicknesses as they interact with varying axle weights and truck weights, I'd like to read them. [quote]QUOTE: PS - Alan Zarembeski (Zeta Tech) on more than one occasion has voiced his displeasure on how some his research has been mis-interpretted or skewed to the point that he no longer recognizes it. [/quote] I have had email correspondences with Alan, and he has never alleged any misinterpretations of my POV's regarding the ZetaTech HAL studies. Again, if Mr. Z has issue with anything I've hypothesized here, I'd hope he'd respond.
