Hello All,

It's been several years since I've posted on here. I'm currently helping my father get his 1950s Marklin collection out and running. while building a layout with 3600 track to run the trains on. I have a few of the 800 series with the double click reverse (such as the 1956 FM 800 among others) that have reverse springs that are a little weak. I am assuming that the early Telex reverse units use the same spring. Are these springs still available and if so what is the part number? I have the standard 7194 reverse springs on hand and I have made them work by stretching them, but they are definitely shorter than the originals. I'd really like to get the correct springs if they are available.

Thanks!

James

I believe the 7194 is the correct spring. I have just been rejuvenating some old locos and 7194 is the spring I have used. If you use a longer spring I think you will find that the reverse unit will tend to pull the armature in when the transformer is at maximum speed.
