This mini series is all about Märklin reversing units. Where they come from, where they go wrong and how to fix them.
This episode covers the origins of the technology, its working principles and the different types of reversing units produced between 1938 and 2006.

This is by far one of the most interesting videos of “the little helper” types that you have ever made. That said by one who has played with Märklin fore the better part of fifty years. Thank you so very much for explaining so clearly, one would almost think that doing this was how you uphold your living.

This is excellent. great viewing, great history lesson. FYI I was reading a model railway magazine from 1909, and this chap had worked out quite a good reversing mechanism, only rather complex. He wired it so a small motor operated directly on the reverser. Now the trick bit is; below 6 volts the motor would turn engaging the reverser. Now the loco motor started above 6 volts, so you could actually come to a complete stop, and start again in the same direction, by just keeping the low volts to engage the reverser motor to a separate low voltage supply. I'll have to dig that magazine out again, as it was extraordinarily complicated.

Thanks a lot... Bing or Trix did something with low voltage in 00 too, but without an additional motor. I think reversing still relied on current interruption, but it worked in a way that the stop position on the transformer ran at a couple of volts, just under what the motor needed to start, and the reverse position was at 0 volt. They also had remote uncoupling in the 1930s, many years before Märklin.

Oh dear, this one completely went under our radar. We've had no bell or anything but have also been super busy this week, lol. However, better late than never. This upload is without doubt one of the best 'little helpers' you've done so far, giving a profound insight of the development of the reversing system. Wonderful 👌

What matters is that you watched it, not when you watched it 😉 It is always quieter this time of year, the gardening season is well and truly here... Have a good weekend.

Excellent video, thanks! Indeed, in most even derelict models that I try to give a new and happier life, it is almost never the reversing unit that shows a significant problem. I do take them apart usually to give them TLC in the form of cleaning, polish the contacts, check the springs, and every now and then some (slight!, careful!) bending of the switching part for fully reliable operation. Also, recently in a 1963 3000 the coil wire was broken but gladly I could pick that up and lead it out once again. Looking forward to part #2, thank you for excellent and entertaining videos just as these ones. Cheers!

I miss the stop with light on function. I think it was very fun to be able to immobilize some lovmcomotives on the tracks while keeping other running without having to use insulated sections or signals

@The3rdRail 2 ай бұрын

It wasn't a 100% safe by the looks of it. On the few locos I have, when more than a few volts is applied, the reversing unit can change over and the locomotive set off... Also, isolated sections are still required if you want to be able to change direction on other running locomotives at some point 😉 Thanks for the visit! Have a good weekend.

This really is an excellent and dare I say 'professional' video. Others have put up explanations but they have suffered by being too brief. You have invested the time to go through all the different aspects with good relevant demonstrations, pictures and video close ups. The motors and reversers are one of my favourite parts of the hobby and one of the reasons why I changed back to analogue from digital. I missed the clicks and buzzes! Thank you.

Thanks for another great video. I have my dad's trains from 1957 including a CE 800 like yours with the two pulse reversing. I'm looking forward to your next video on maintenance as my recollection is you can adjust the reversing spring to reduce the jump. It will activate more easily if the spring is looser. If the spring is too tight, then it can just race forwards and never activate the reversing mechanism. I'm interested in your opinion on this. Thanks again.

Great Helper video, like all the others! Can you touch on the TELEX reversers and how to adjust their springs' tension? The hook is quite a bit stiffer than the RELEX reversers

@The3rdRail 2 ай бұрын

Thanks! Part 2 will feature a bit about springs for sure.

A small question : are those electronic reverser compatible with the old blue transformers and the very old blue transformers or is the inversion voltage of the those old transformers too high for the delicate electronic components ?

Answer in part 2.... Hint: it depends...
