Posted by Broadway Lion on Fri Jan 1 18:26:29 2010, in response to Re: Def Of Late Trains:, posted by ClearAspect on Fri Jan 1 18:10:36 2010. I asked Br. John (he is our maintenance manager) if he had any 1 RPM motors (he NEVER throws anything away) for as I had mentioned, I was planning on building a machine to start my trains from each station after they had made the stop.Well, what do you know. He had the most perfect timer switch for me. A 60 second run time and six wheels and switch sets. I will use four of the switches, so that I will have four "start wires" running around the layout. I will then be able to have a start time at each station of 0, 15, 30, or 45 seconds. The one I select for a particular station depends on the running time + the dwell time from the previous station. So I will start at 242nd street on the even minute, and then I will program each succeeding station stop by connecting its start relay to the proper start wire. I will apply about 10v DC at perhaps 5 Amps to the entire layout, which will be powered up at all times. (Train sets are wired for all-wheel pick up) As the last car of a train clears each of two gaps bridged with 10 ohm and 15 ohm resistors it will slow down. As it clears the last gap into the station it will stop until the time clock pulls its relay to let it continue on to the next station. The same trick with the resistors on the track gaps will allow it to pick up speed properly. This afternoon I was (until I was called back downstairs to sell some wine) perfecting the resistor system at the South Ferry Station. The project *is* looking good, and I am impressed with my own progress. Now I will have to rebuild the other four trainsets with drawbars, 48 wheel pickup, and constant lighting. The lighting is battery powered, and so constant during the run of the train. A magnet built into the terminal stations and yards will shut the lights off (a reed switch, don't you know) when the trains are not running. ROARING |
