Absolutely. On my line up here (Springfield line) I have on more than one occasion overheard crews saying things like "These GEs need to be retired." But I'm sure when the Siemens equipment comes they will hate it at first initially and pine for the GEs. It happens in my industry (IT) all the time as well with new software, operating systems, etc. Many of us often times hate the new stuff and pine for the old days but eventually you have to adapt or risk being left behind because in most cases the technology is not going to go in reverse so you can adapt or become obsolete.
