Well Guys,
I was hoping that subject would get your attention.
We have had a few posts lately about engines that wouldn’t run fast, and lots of help for the posters on how to diagnose and fix.
I have the opposite problem. I have a few steamers that run great at higher voltage, but not so much for slow speed operation. One example, I played with today. This is a 303 4-4-2 locomotive, that I just aquired. At anything above 11.5 volts it runs great. In fact at full voltage I think It will leave the track and become airborne should I choose to let it. I am using an 18B transformer, 175 watt version.
At under 11.5 volts it will just barely move, and hums pretty heavily. I have just had it completely apart, cleaned lubed, new brush springs, and cleaned the commutator up all shiny and cleaned the groves. The brushes looked great, so I didn’t change them. The light is bright, and it smokes better than any other locomotive I have.
I do not know how to check the amperage draw, although I read in the service manual that it should draw no more than 2 amps pulling 4 cars, or .175 with no load.
So how does a novice who has been playing with trains on and off for 50 years test that amperage draw? And what else can I check to see if I can get it to run better at slower speeds, less voltage. I have a 293 4-6-2, and a 312 4-6-2 that act similar, but for today I will stick with this one and use what I learn to check on the others.
Thank you,
George
