The original 1044 transformer that was given to me with my first train set has died. I would like to repair it are parts available? Thanks

Looks like the resistance wire is cooked. Are there other things wrong? The resistance wire is 1044-56. It seems that some people replace them with 2.5 Ohm resistors.

It's that resistor? Did it get damaged mechanically by the movement of the whistle lever? You probably could replace that with a different power resistor, given the room. What size is it? Try measuring what is left of it. I see that Brasseur's has some 1044 parts, but no resistor.

It's part number is Lionel 1044-56 and Olsen's Train Parts shows it for .25 from Lionel back in the day, but I don't know if they really have them and if so, what the real price would be.

Yup, good eyes. Joan of Arc looked better than that wire.
While you have it exposed, you might consider replacing the rectifier disc assembly with a 16 amp diode to help the whistle.
BORMAN4 The reason I took the transformer apart was the it was not working correctly with my TIU. the voltage was fluctuation between 11VAC and 14 VAC. I was expecting to see the voltage control swiper not making good contact. What you see is what I found the wire is broke in two pieces what watt 2.5 ohm resistor should I use?
The broken wire is a nicrome resistor. I have heard that these can be upgraded to modern resistors. This seller (no affiliation or recommendation) has these available:

You should also note that the 1044 is a relatively small transformer only able to deliver 60 watts or so and comes up short of delivering the traditional 18VAC used in today's command systems and so it may be that there is nothing really wrong principally with the transformer other than being overloaded.
Ok I have used it since 2010 with no problems but when I hooked it you this year it would not work I am looking at a newer transformer for the TIU. Thanks
Get yourself a good LW25, and you will never look back....

Question: What wattage 2.5 ohm resistor should be used ?
I would buy a 100 watt resistor at the least and higher would not hurt.

The transformer is 80 watts I think. Probably about a max of 4 or 5 amps amps. So if half the current went through the 2.5 ohms, that’s about 10 watts or so. That or anything over that which will fit should be fine.
thx
As a last resort, you could contac www.tranz4mr.com, and see if he can come up with a solution for the resistor. Worth a try.
I have a 1044 for parts with the same issue. You could replace it with a 2.0 to 2.2 ohm resistor or order part 1033-103 old school long white whistle wire resistor that was used in almost every other whistle controller from any Lionel parts dealer for about $2
What is a LW25. I know what an LW is, it's a great transformer. Just get a 1033 90W or an LW 125W. If you have 022 switches get the LW. The 1044 was a piece of crap.
The resistor is part of the whistle circuit. It takes some of the load off the rectifier disc after the relay has picked up. It should have nothing to do with the voltage fluctuating when the whistle was not in use. As the OP stated the sweep arm could be the problem. I would start with the circuit breaker. Jumper the circuit breaker and add an external circuit breaker, maybe 4 amps, and see if this fixes the problem.
