Easy Crossing Signal Circuit

For years I have been reading articles on EASY crossing signal circuits. After reading these articles and gathering all the parts needed (not that simple since my local Radio Shack is gone) I have several failed attempts in my shop. Now after all these years my prayers have been answered.

Layout idea: "New Alton Shops"
For years I've learned so much from the members of MRH forum through lurking – reading others' questions and the collective wisdom of the MRH. I'm thinking it's time I put my layout design sketch out here for some input and feedback.
Changing Major Directions from my Current Layout to a New One
I started a blog in 2017 to document the creation of my Z scale Alpine layout (all Marklin locos and rolling stock with mixed products for just about everything else). You can see my posts at the end of this page.
I went with Z scale because I wanted to make the most of a layout in a limited space and I had bought some Marklin Z rolling stock, locos and track many years ago for "the day" I would start a layout.
AR1 problems
I see a reference in the last post to the AR1 reversing loop having its own power connection. This is
not shown on the instruction diagram. The only connection show is from the AR1. Please verify.
Power pack
What is a good wattage power supply for a medium sized one man layout? I have seen up to 125 watts, is that too much? I will run a single engine switching layout. Thanks in advance. Mike H.
Sources of HO resistor wheelsets?
I'm looking for sources of pre-made HO scale 33" 10K ohm resistor wheelsets — as opposed to wiring my own.
I'm aware of:
- Jaybee - jbwheelsets.com/resistor.html (listed as "temporarily not available")
- Logic Rail Technologies - logicrailtech.com/dws.htm
Other sources?
Simple electronics! I need a resistor I don't have...
I have a box nearly Full of 1/4 watt resistors... but I'd feel better using 1/2 watt in a simple circuit. (
All tutorials I find handle the calculations of resistance as resistors are combined. Fine... series is additive, parallel is inverse average... but watts??? I'd think it's distributed over parallel resistors, and want confirmation before I fry things. How small can my parts be before they don't perform?
Sensor Part Minus 1
Is is a Video on sensors, this is about types of sensors that can be used on both DC or DCC. If you ever wanted to do sensors or add block occupier light on you control panel this is part one of or minus 1. ( I did one last month but this will be a broader look at sensors.) I look at more types but the 4 shown here I think are the most useful. 3 can be used on DC and DCC one is for DCC alone.
Hope this is helpful if you are looking into sensors and what can I use.
Mike
