Checklist for your module(s) before the next show:
Over the years, our fellow tech guru has run into a number of common electrical problems and track alignment problems which are best solved before the shows. Here is a list of items to check:
Check electrical connections at the terminals while the module is laying on it's side (PMC recommends the use of terminal blocks for the bus wiring).
Look for any loose wires, especially around connection points.
Fix loose connections right away or make a note to fix them as soon as possible -- but not at the show.
Purchase an electrical meter. Why? Simply applying track power will not always reveal power faults such as problems with loose plug connections, broken wires, or cross wiring.
Verify that the track is "in-gauge" by using the NMRA's track gauge. It is well worth having one around.
Verify that your switches are functioning (both manual and electrical). This includes running locomotives through the switch to ensure electrical conductivity. You can use a meter to check this as well. Make sure the blade is contacting the stock rail.
Bring trains to run... It has happened before - modules show-up but no trains.
These basic items usually only take a few minutes to perform, thus saving time during module setups.
Potomac Module Crew's Operating Sessions:
Throttles: PMC uses Digitrax for its electronic operation. To operate on the layout, you need to use a Digitrax throttle.
De-railed trains cause traffic jams. Obviously, this is frustrating for the operator. But any stoppage, ends up affecting the entire mainline. Here is a three step sequence to follow when running a troublesome car:
1. After the second time a car disconnects or derails, turn it around.
2. If the car still disconnects or derails, move it to the rear of the train.
3. If the car still disconnects or derails, remove it from the layout, note which end (the "B" or brake wheel end or the "A") is having the problem, and fix it before the next time you run it.
Although these steps above will work mostly for freight cars, steps 1 and 3 do apply to passengers cars.
