N Scale SD40 2 Switching

[@tommynorwood5184]

That was a good video. I liked the different angles you filmed the session. Just something about a Southern loco long nose forward. Thanks for sharing. 😎😎 👍

[@AlleghenyNorthern]

thanks. i tried to focus more on the angles than showing the switching job - wanted to focus as much as possible on the locos and the scenery.

Great video and cool layout. Also nice to have somebody else do some switching in N scale. Switching sessions on YT seem to be H0 scale 90% of the time. Would love to get an engine with sound myself at some point - maybe even a SD40-2. Keep up the good work!

[@AlleghenyNorthern]

Thanks! Ah, the SD40-2 - some of best sounds come from that loco!

Awesome job

Was surprised to see Altoona Pipe & Steel. I live in the nearby town of Duncansville. Want to get a layout going at some point. Probably HO or N. Had the O Scale up around the Christmas Tree. First time out of the boxes since I got it for my son back in 1998.

Great looking engines! Your videos of the layout are inspiring. Have the locos smoothed out for you after their extensive break in?

[@AlleghenyNorthern]

Yes, they're running well.

I just saw a comment about the stutter in the SD40’s by @jrbokleman. “There is an error in the default programming of the decoder CV52 or BEMF K slow. It should be set higher than CV54 by 5-10. CV 54 was set to 35 and CV 52 set to 20. It should have a higher value. Just change CV52 to something north of CV54 by 5-10 and it should smooth out nicely” just thought I’d share

[@AlleghenyNorthern]

appreciate the information. i don't seem to have much stutter now, but i'll check the CVs out just to see. i did test the resetting of the BEMF on one of them and didn't see a difference so i'm curious to see what 52 and 54 read now.

How long is the break in period to get them running smooth?

[@AlleghenyNorthern]

Mine ran about 4 hours which admittedly is a lot. they probably calmed down in the first hour or so though. I did mess with the CVs as some folks had recommended, but i didn't notice any significant improvement in operation.

[@Fallenhalo88]

Did you need to speed match the two at all? And how do they speed match with other Scaletrains locomotives?

[@AlleghenyNorthern]

These two run together without any speed matching. they ran the layout separated for 4 hours during break-in and never caught up to each other. I haven't tried pairing them with the other ST locos yet.
