Marklin insulators only break the connection for a very short distance. If you use insulators, can it be a problem for the loco when the front wheels gets over the insulator and on the second transformer and the back wheels are still before the insulator on the first transformer? Aren't all loco wheels electrically connected to the track? Isn't this two sources of power at one time? Thanks Ron

Yes, for this short period both power supplies are connected together, however, this isn't a hazard. For modern active controllers (like Marklin's) the higher voltage controller will take over, so you'll be driving with whatever voltage it is set to. For old fashioned rheostat controllers you get a voltage somewhere between the setting of the two controllers. In any case, it will never exceed the higher of the two settings so will be safe for your locomotives.

Cheers

better to use insulator track to separate two circuits? Not sure, pls advise

The insulated joiners are designed to be used as a pair and whilst I haven't tried using them singly, I suspect there would be problems if you did.

Of course, this does mean making an extra power connection for each section of track, but otherwise it's no great hardship.

Be careful when removing the original joiners though, especially from pointwork, as it is easy to rip the rail from the sleepers if you're too rough!

Reading back, I think I may have misunderstood the question - apologies for that.

To my mind there is absolutely nothing against using the insulated track joiners other than that you have to remove regular joiners from track sections and have to make your own electrical connections to the new sections.

Admittedly, they do look flimsy, but I've had no problems so far, even when joining to sections of flexible track.

For certain it's a lot less expensive than using ready-made isolating track sections, although the insulating joiners aren't cheap as you have to buy them along with lots of un-needed metal ones. I managed to by a big bag of insulating joiners on ebay for a reasonable price.

Hope that comes closer to answering your question!

All the best

It will be fine - I was surprised how well they work, despite their small size.
