Im gonna ask, what is the best type or brand of AA Battery should I use for my Tomy Talk N Action engine to avoid blowing the fuse? I don't want to break their electrical circuits.

So I take it there is a problem with these or just something you have experienced as I haven't heard of this before. Off the top of my head, I assume that the fuses blow because of too much volts? Have you tried rechargeables which carry 1.2 vs the 1.5? Of course I have no first hand knowledge as I have none of these trains.
I do have Duracell Batteries that are 1.5 Volts and I also bought batteries from Dollar Tree as well.

So do the train fuses always blow when using regular batteries?
TNA engines have a rating for 1.5V AA batteries so just any 1.5 V AA batteries should work.
Also TNA engines, at Least from what I've observed on mine, don't feature any fuses , they do feature resistors and those transformer any excess energy into heat. Even if one is damaged you can just remove it not necessarily replace as it's not entirely essential.
I have seen fuses (in Talk n Actions and occasionally other Tomy trains) made up of a small frame of brown PCB substrate material with a single thin wire across it that will burn up if too much current is being drawn through it, they are usually located between the two layers of the battery compartment. I have not had any issues with any particular brand or type of batteries blowing these fuses, but if you experience it regularly it is probably because the motor is worn out or the gearbox is putting more strain on it and it is requiring more current from the batteries to operate correctly. The fuse doesn't know the difference between the toy being legitimately broken with a short circuit in the wiring somewhere that could cause the batteries to heat up and the motor just needing to draw more power to run properly, it just burns up when too much current is passed through its wire. You could substitute in a slightly thicker wire that would not burn up as quickly if you are running into problems, or try servicing the motor and gearbox and get it running smoother.
As mentioned by Super, there are several brands of Ni-Mh rechargeable batteries that operate around 1.2 volts instead of 1.5 which may help prevent the fuses from blowing. Eneloops are the "classic" style but Amazon, Ikea, and companies like Panasonic, Sanyo, and many others produce similar rechargeables that can mostly use the same chargers and perform similarly. I have run Talk n Actions on these batteries before and I don't remember having any issues (other than the issues Talk n Actions normally have)
I have a
website where I have been writing about and photographing many of the sets and pieces that I find interesting.
If anything I would use tier 1 batteries (Energizer/Duracell) rather than less expensive Rayovac or dollar store brands.
Play nice & have fun!!
