I would like to share the outcomes of a little experiment I did this morning. Just out of curiousity, I have calculated the scale speed of my T gauge class 103 train with a normal Eishindo speed controller.
The test track was made of 12 120R curved tracks and 2 6cm straight tracks, with a total length of about 87 cm.
First, I tried the slowest speed I could run the train reliably, without to much stuttering. A lap took 14.03 seconds, which comes down to a speed of 0,2232 km/h. In the real world, this would be a scale speed of 100.5 km/h, or 62.4 mph.
With the controller fully open, the train needed 2.85 seconds for the full lap, with a speed of 1,0989 km/h. Times 450, this is 494.5 km/h, or 307,2 mph. Not bad for a class 103 .
The slowest speed is a little higher than I expected, but actually quite acceptable for an average commuter train at full speed. _________________ Some thoughts on T |

Good work on your experiment, Jes. Just for the record, the service speed for the class 103 EMU actually is 100 kph .
Good reference site for most current Japanese trains: http://homepage3.nifty.com/canada/top~en.html . _________________ Kind regards

Today I had one of my trains take 25 seconds to travel around the standard 132.5mm radius oval - 12 x curves and 4 x straights. _________________ Darren,

Darren,
That's about 70 km/h!
Did you use the Eishindo controller?
Who said T trains only run at unrealistic speeds
By the way, that's a very good site indeed, Dominik! _________________ Some thoughts on T |

Yes, I was using the Eishindo controller - on batteries too.
I have two trains, one orange, one blue. From the beginning, the blue one ran slower and has continued to slow over the last two months. Its top speed is now about the same as its slowest speed when I got it. I'm not sure why it has slowed so much, but I'm not complaining. The orange one has also slowed, but not as much.
I took some video today and shall upload it when I get time.
Has anyone else had their trains noticeably slow down over time? I am wondering if mine will settle down or continue to keep slowing over time until they don't move at all. _________________ Darren,

Hello Darren,
the same happened to me.
I'm using 3 different types of locos.
One is called by me high speed , the next lower speed, the last one low speed loco.
I disassembled the low speed loco to see what's wrong with it.
Nothing to find.
All contacts have been checked, wheels are clean, gear is running well, the springs are also OK.
Everything seems to be in best condition.
Test run at the cleaning pad was successful.
After assembling, the same as before. Only slow speed.
I have also disassembled the high speed loco and compared it with the low one. No differences visible.
The assembled high speed loco runs as good as before>> I felt very happy about that!!!!!!
I gave up to improve this devilish slow loco.
regards
