End of the story... The machinery needed many repairs : warped or broken parts, too much backlash, wiring off, inductor loose winding, etc. ![https://nsm09.casimages.com/img/2024/07/17//8SQ3Sb-P1200811.jpg](https://nsm09.casimages.com/img/2024/07/17//8SQ3Sb-P1200811.jpg) ![https://nsm09.casimages.com/img/2024/07/17//9SQ3Sb-P1200814.jpg](https://nsm09.casimages.com/img/2024/07/17//9SQ3Sb-P1200814.jpg) ![https://nsm09.casimages.com/img/2024/07/17//ASQ3Sb-P1200815.jpg](https://nsm09.casimages.com/img/2024/07/17//ASQ3Sb-P1200815.jpg) I rewired the circuit with two modes : AC and DC. * In AC mode, the engine only run forward, no matter AC or DC supply. * In DC mode, the engine follows the polarity of the DC current and can go forward or reverse direction accordingly. The original circuit was a manual inverter offering forward and reverse direction. since it was broken, that was the occasion to experiment... Schematic : ![https://nsm09.casimages.com/img/2024/07/17//8SQ3Sb-P1200813.jpg](https://nsm09.casimages.com/img/2024/07/17//8SQ3Sb-P1200813.jpg) As expected, the performances in the DC mode are a little bit inferior vs. the AC mode, due to the insertion of the bridge rectifer. I hoped to compensate the difference by the addition of a 1000µF/25VDC capacitor accross the + and - of the rectifier bridge in DC mode, but conversely it degraded the performances further... So no way ! Picture of the finished engine - OK, we know now that the paint finish quality is not premium : Everyone has their own limits... ![https://nsm09.casimages.com/img/2024/07/17//BSQ3Sb-P1200816.jpg](https://nsm09.casimages.com/img/2024/07/17//BSQ3Sb-P1200816.jpg) ![https://nsm09.casimages.com/img/2024/07/17//BSQ3Sb-P1200819.jpg](https://nsm09.casimages.com/img/2024/07/17//BSQ3Sb-P1200819.jpg) The restored/modded "Daphne Blue Montagnarde" along with her 1935 original sister "Paris-Orléans Montagnarde" : ![https://nsm09.casimages.com/img/2024/07/17//CSQ3Sb-P1200826.jpg](https://nsm09.casimages.com/img/2024/07/17//CSQ3Sb-P1200826.jpg) ![https://nsm09.casimages.com/img/2024/07/17//CSQ3Sb-P1200827.jpg](https://nsm09.casimages.com/img/2024/07/17//CSQ3Sb-P1200827.jpg) OACE

Very nice! You made something old new again! That locomotive reminds me of the old original Lionel locomotives of the 1916 era, Look up the little "O" Gauge #150, 152 'short' electrics. Very similar! Did you do the drawings?
Also, was the original switch a reversing switch? I see an original one on your other unrestored locomotive. Your work will allow this little loco to live for another century!

By the way ... What do the cars to this set look like? Passenger or freight? Pictures? Thanks.

Your work will allow this little loco to live for another century! Thanks mrmeep ! Yes ! The LIONEL 150, 152, 153... Oh, I would like a 150 ! One of these days... You call them "Steeple Cabs" locomotives in USA, right ? Yes, I do the drawings... Un petit dessin vaut mieux qu'un grand discours ! I very like drawing... Exact : the original switch of the " La Montagnarde" was a manual reversing switch. It permuted the two poles of the inductor. That's what does the original switch on the preserved Green PO Paris-Orléans.These little LR Montagnarde are well built, indestructible and fine runners. They can be bought locally for circa 30 (rolling project) to 100 (mint) Euros depending on the cosmetic conditions - way much less for me than a LIONEL 150 project limit derelict imported from USA...

By the way ... What do the cars to this set look like? Passenger or freight? Pictures? Thanks. I do not have the original cars, but they looked like the ones in this set below - among others : ![https://www.ivoire-france.com/ddoc-456723-572f292d3b47c91c82936ec8512c1310-568268_1055394497.jpg](https://www.ivoire-france.com/ddoc-456723-572f292d3b47c91c82936ec8512c1310-568268_1055394497.jpg) I use my Montagnarde with a little set of little cheap-light Hornby-Hachette reissue cars of the 90s, that were sold with the French magazine Loco-Revue, IIRC. These little cars are completely discarded, and so can be bought for peanuts in new condition. I was even given this set below : ![https://nsm09.casimages.com/img/2024/08/23//Jb8HSb-the-Hornby-Hachette-RI-car-set.jpg](https://nsm09.casimages.com/img/2024/08/23//Jb8HSb-the-Hornby-Hachette-RI-car-set.jpg) OACE

Very nice! "tres agreable" (couldn't add the extra marks, sorry)
Your mechanical and electrical drawings are EXCELLENT!
Drawing like this is a lost art here in the USA where everyone now relies on computers to do this work. I remember taking mechanical drawing/drafting in high school many decades ago.
I still prefer to do my own drafting/drawings.

I still prefer to do my own drafting/drawings. Yes ! We have the same phenomenon here in France... That leads to the problem that simple drawing/drafting int'l normalized conventions are gradually ignored ! And yes : hand drafting/drawing has it charms... I plan to acquire some other project "Montagnarde" locomotives, and will restore them with the main chassis painted in unusual joyfull 50s-60s guitars and cars colors : Surf Green, Shell Pink... Like this one in Daphne Blue. OACE
