Hello people new to the sight so here is my first post and problem.Brought a prodigy 2 at warley the weekend and a dcc ready class 66 i've since fitted a tcs m1 decoder and all seems fine,occasional stuter around one bend but i can live with that,now i have a simple very large loop 25 foot by 10ft its in the loft now to this i've added a sid
ing.The problem is when i manually flick the point the train stops! and i just get a buzzing noise every so often and the train slightly moves? now i'm useless at wiring and haven't a clue really so any help appreciated. Its 00 gauge ,peco code 100 track and streamline points. I'm sure its due to wiring but i haven;'t a clue!! thx

I think you will find that a short occurs as you change the point as the contacts switch the frog polarity, I seem to remember this has been discissed on on of the forums before and you need to cut the wires unde the point and add a switch to change the point direction and polarity at the same time.

Its also a good idea to put in insulated joiners to both rails and then wire the siding into the main bus, thus making it all part of the layout.

You do not say if the points are insulfrog or live frog so I think they are live frogs to get this problem.

You do not say where the engine is when you flip the points. Is it on the oval, or is it in the siding?.

If you have a short as Mike says, your prodigy green lights on the controller will be flashing alternately, and you may also hear a buzzing as the fan comes on. ( I have a Prodigy)

If the engine is on the oval, does it start off again when you flip the points back?

I use Lenz Silver decoders, as I find them very reliable and resistant to problems.

the train is on the main track and yes they are live frog points which i was told to buy for dcc! so basically all the points will have to be wired then? i thought this was the hole point of dcc to stop all those dang wires!! the decoder is a tcs m1-uk. Can you explain it again about the point wiring as i'm confused wiring and polarity baffles me thats why i went dcc not dc!! good job i only have 1 oval down at the moment then?? oh thanks for the replies.

You have a short circuit somewhere. Your trains would stop whether your layout was dc or dcc. Take a close look at your track plan to see where the left rail power meets power to the right rail.

***You must add an insulated rail joiner on the heel of the point (near the frog) on the maim line. One insulated joiner will fix your short circuit problem. This is exactly as per the Peco wiring instructions which you have to follow! This is no different whether its DC or DCC.

You should also add more power feeds than a single pair on a larger layout - This may not be an ussie but as your layout grows and ages, you will not get good running unless you so as rail joiners do not conduct power reliably after a while....
