You could try running a UPS to stablise your power.

With switching-mode power supplies there shouldn't be any fluctuation on the output side.
If there are fluctuations even with SMPS then there is something seriously wrong on the input side (voltage at the wall outlets). A UPS could fix that.

As discussed several times before: using a Delta Control as a booster would give you a higher track voltage and some trains would be able to go faster while others would keep the same speed.
Higher track voltage increases the wear on motors and light-bulbs.

You can get the same effect by using a power pack with a higher output voltage for your MS2.


The booster recall program is a different story: they used a cost-optimised scheme for the first booster generation. The design was so cheap, it was impractical to use. They came up with a new design and replace old boosters free of charge.
Boosters with the cheap design can also be found inside the CS2 60213, inside early CS2 60214, and - if speculation is correct - inside the new CS3 60226.
Never make the same mistake twice. With the 60226 they made a variation to the mistake, leading to the effect that newer 60214 will work in Master/Slave mode without restrictions while older 60214 have restrictions when used in Master/Slave mode.

In the last century Märklin were famous for their clear and simple system.

Do you know what hardware revision does not have the restriction?

I am not quite sure what you are referring to by power fluctuations in your house. Ontario Hydro has a pretty stable network and your main breaker should be providing your wiring with a standard voltage. If you are experiencing brown outs or similar, say, when you turn on an appliance, there may be too much plugged in to that particular circuit. What I would recommend is that you try running an extension from another room (on another circuit) to see whether that solves the problem. If yes, you may decide to call an electrician to install a separate circuit or to move the outlets in that room to a new circuit with it's own breakers and less of a load.

I do not think that voltage fluctuations on the mains would greatly disrupt the output of a model train transformer AC or DC unless the entire circuit (mains) was being disturbed (as described above).
