SoundTraxx 810140 | CurrentKeeper™

The current keepers that I purchased have made the difference in operations and performance. I was not sure that they were the answer to fits and starts with my locomotives, but they were precisely what was needed. Thank you for another outstanding transaction!!

Great addition to SoundTraxx 884007 | TSU-2200 Steam-2 Digital Sound Decoder, especially for old locomotives with poor pickups. I tried it on an old Bachmann HO Scale Niagara 4-8-4 NYC, and an old AHM Rivarossi HO 2-8-8-2 USRA MALLET and it work great!

They work very well in getting the locomotive over turnouts where power and sound can be briefly interrupted. They are rather large and won't fit in many locomotives.
