Lionel X246 converted to 9 Volts AC (Wiring Question)

[ADCX Rob]

You could convert it to DC just like Lionel did:

Hello !

and welcome !

if I am understanding your question, it sounds like a very custom conversion, and probably not something many people have attempted.

But, possible. Please post a picture when you finish. I am hearing 2 issues to overcome :

1. AC to D.C. conversion. 

You could probably find this on the internet, fairly common circuit.

2. Limiting max voltage. Totally do- able.

this sounds like " constant lighting" circuit. An example would be LGB's upscale engines that have a 5 volt headlight and smoke unit. At 5 volts and above, the headlight and smoke unit are at full capacity, the circuit limits it to no more than 5 volts.

again, it is probably out there on the web, sorry I can't offer more than that.

Best of luck, let us know how it turns out.

I'm skeptical that a CD DC motor will fit in a Scout locomotive nor be powerful enough.  It seems to me to be a very impractical choice for a motor:   https://www.youtube.com/watch?v=gy1ezudajjc

What is the purpose of putting such a motor in the Scout, instead of a universal motor?  Are you okay with not being able to reverse the new motor?

What AC track voltage do you want to have correspond to 9 volts DC at the motor?

Hi, this is my first post on Classic Toy Trains!  I do have a question to ask, I've been wanting to convert an engine, one that has no motor in it to use a 9 volt CD DC motor that I picked up online, I want to convert it into a 4-4-2 as it used to be a 2-4-2 replicating a engine from a parody series online, I would like to convert it to AC, But resist excess voltage from getting into the motor thus avoiding wearing out the brushes, how many diodes would I need exactly and how would I arrange them?  

Thanks for Any Help, it would be appriciated

P.S. this engine used to be an ex - Lionel Lines locomotive or will be soon, it is currently No.246 and the model will have modifications done to it structurally to make it look slightly british. with an added bufferbeam and a paint job almost like the LNER locomotives of the Pre-Nationalization companies before there was British Railways, it won't be entierly modified though.
