Posted by tracksionmotor on Thu Feb 8 20:53:18 2007, in response to Modern Subway Cars vs. Older Subway Cars (pros, cons, memories, thoughts)), posted by subway nutz on Sun Feb 4 17:55:21 2007. I've had my hands into R16s/17s/26s/29s/33s/EPs/68s/142s and did a tour of the R110 (on my own.) IF you work 'New Tech,' basic inspection is easy because so many systems go under software control and you lack direct electropneumatic systems to deal with. IF you work 'Old Tech' you are faced with electropneumatic systems to inspect and test.'Line in the sand' is troubleshooting problems. With 'New Tech,' many problems are embedded in software. 'Old Tech' takes a bit of electromechanical skill...and some luck...to troubleshoot. I'm not into nostalgia....the Redbirds taught me craft....I can look at something without the aid of a 'Portable Test Unit' (laptop) coming up with a preliminary diagnosis just by what is 'in my face.' A computer cannot pinpoint broken parts....takes a Car Inspector over Quality Assurance Inspectors to look into and get really dirty. I prefer older DC electropneumatic trainzzzz. I work Bombardier M7 heavy passenger railcars. My new post on inspection of M7 HVAC systems is on tracksionmotor.blogspot.com I just did the inspection of 4260/4261 today of HVAC rooftop seals.....it is very time consuming like changing out HVAC units four times in one day. Crew took pics of me and I will post when I receive them. RRCI Peter |
