Lionel 1044 transformer whistle control resistor question

That resistance wire is about 1.5 ohms. It is the same resistance used in most of the post war transformers with whistles. They all used the same rectifier disc, so same resistors.   You could look for resistance wire part ZW-167.  It is still around and is same resistance.

Thanks to both of you. I took out the rectifier and the broken resistor.I ordered parts so I’ll see how it goes when they come in.

Hi everyone. So based on several recommendations from you all, I bought a 6 amp diode and a 1.5 ohm - 25w resistor off the bay to replace the old rectifier/resistor. The old resistor was broken in half - curious.
The new resistor was larger than I anticipated but I worked out a way to get it in there by adding a piece of wire to connect to the inside bracket for the old wire resistor. The diode went in fairly well allowing for my lack of soldering skills. After installation I tested all the post combinations and got relatively close readings to the stated voltages on the cover. Including an increase in voltage when I toggled the whistle throttle. Then I set up a couple pieces of track and put an engine on it and connected the 1044.  Pleasingly the engine came on and increased power when I moved the speed controller. When I moved the direction controller the engine cycled through neutral forward and reverse. And when I moved the controller to the whistle position the whistle blew with a strong sound.

I posted a couple of pictures showing what I bought and the final product. Thanks to all for your help.
