Posted by WillD on Mon Sep 4 20:33:19 2006, in response to Re: Intermediate Station Fare Payment on SIRT (was:Re: Scrap pecking order with R44-SI), posted by Dan Lawrence on Mon Sep 4 17:20:09 2006. Only from a close in orbit. From the moon, Earth looks like a big blue marble.It all depends upon how good your optics are. Turn a crater into a reflecting telescope with an array of hexagonal mirrors adding up to some 100+ meters in diameter and you could probably read license plates from the moon. Of course your telescope could run into the problems of atmospheric conditions, but those would only hamper the imaging for the first few miles from the source, rather than the last few miles as an earth based telescope has to deal with. But then there are much better uses for a 100 meter optical telescope than staring at earth looking for garbage dumps. Since it was mentioned earlier in this thread that the SIR R44s are 33 years old. How old were the B&O MU-1 cars when the last ones were replaced by the R44SI's? The MUE-1s were purchased in 1925 and were largely replaced by MP72s by 1972, a service life of 47 years. Those MP72s were a stopgap measure because apparantly the aging MUE-1s were in such bad shape that they were largely unfit for service and their replacement, the R44SI or MUE-2, would not be delivered for another year. Considering the amount of time required to get new rolling stock acquisitions through bureaucratic red tape now would seem to be the time to start the ball rolling on replacing the R44SIs around the time they turn 40. IMHO the MTA should look carefully at their options with the SIRT, whether they want to keep it compatible with the NYCTA system, or if it makes more sense to make it LRT compatible. |
