The All Gauge Model Railway Club Inc has introduced two initiatives to improve the enjoyment of running your trains at your club.
Firstly, Amp meters have been installed on the Inner and Outer lines of the HO/OO layout upstairs for members to keep track of the amperage their locos draw. This will allow you to make sure your locos draw less than 2 Amps on each controller as this is the maximum the controllers can deliver without causing overheating and damage to the controller units – such as happened recently when one had to be replaced and sent to be repaired.
Single locos should draw between 200 to 350 milliamps with normal running while some Athern models may draw significantly more. Some members have run large double-headed 6 wheel bogie pickup/drive diesels, and maybe another train at the same time on the same line. This is only OK if the total amperage drawn is less than 2 Amps.
The meters are scaled as 5 Amp meters where each amp scales in 10 indications to the amp. Therefore, each one 10th of an amp is 100 milliamps as there are 1000 milliamps to the single amp. So the average unit should indicate around 3 & one half on the scale when running “imperial” as indicated on the controllers. If you run the opposite way, as in the “USA” and wherever else they run on the right side of a pair of rails, the meters will register a negative reading. This is not an issue for the meter but if you think you might be overloading the controller, reverse your loco slowly and you should get a positive reading which will represent 80/90% of the negative reading which is occurring with normal running in a “USA” situation.
The Watts your unit is using may come up. This is the power (EMF) your unit/s are using and this is calculated simply as Voltage times Amperage = Watts. So, if you are drawing 350 milliamps and the controller is on 10 Volts, you are using 3.5 Watts to drive your unit/s.
Not all members are on the Google email system and every member won’t see this notice so please make this a topic of conversation at the club and upstairs while running your trains.
Secondly, three of the electric points in the Engine Yard have been brought back to life. It is now possible to run your trains through the Engine Yard’s reverse polarity loop more easily by using the now-electrified points. It is no longer necessary to walk around the yard, to hand-change the points near the time board.
Mid April, our membership is: Life 4 – Ordinary 38 – Honorary 1 – Associate 3 – Families 6. We welcomed recent new member Daphne Huang. Jason Somerville has made application to join as a Family Member with his partner Stephanie Surawski. Jason and Stephanie have already attended the club several times and Membership Officer Rod Travis will recommend their acceptance to members at the next Members Meeting.
Last, but by no means least: AMRA asked AGMRC to assist with security at their Brisbane Model Train Show in May. We were pleased to accept and a roster of volunteer members has been drawn up to work over the two days. They will wear their AGMRC shirts and/or member badges. One of the rewards for helping is placing our flyer promoting our July train show and November open weekend in the 3,000 AMRA show bags. These show bags are a replacement for their show programs of past years.
