I didn't say that PATH will necessarily replace the trains, only that it might choose to do so in less than 25 years. We have been assuming approximate lifetimes for rapid transit EMUs of about 35-45 years, but PATH is in no way bound by that assumption. It could be the case that PATH chooses to opt for a 40 year lifetime, or it could be the case that the PA believes that PATH is benefited by newer cars and it is open to replacing the PATH fleet at relatively quicker intervals more on the order of 20-30 years.After all, NYCT went with the GOH option, but had they not, R62/As and R68/As (and a 60' or 67' model based thereon) could have replaced the entirety of the then-existing NYCT fleet. Given the not insignificant cost of the GOH program, perhaps it would have been more cost-effective to replace the entire fleet at that point. It would certainly have made things less interesting for me as a railfan, but there is nothing to suggest that the 35-45 year lifetime is a target to shoot for irrespective of other costs and efficiencies. Further, LIRR may choose to replace the M3s with M9s, although this decision has not yet been made. So that is another example of how the 35-45 year lifetime may be at odds with recent practice. |
