And the trains themselves. Here's a bit of sound from a Belgian AM62 EMU, recorded between the driver's cabin on the right and the control cabinet on the left:

Speaking of which: does anyone have or could someone point me to an audio recording of a contactor engaging... the typical klonk and the buzz?
Let me work on it. I have a contactor in a project that is almost finished (and was almost finished last week, and was almost finished last month... and was almost finished a year ago).
Short version of the story:
I have rebuilt a control box of a spa (hot tub) using a contactor, relay and electro-mechanical switches even including bi-metalic strips.
The old box was 120V only with a 1.2kW heater element and safety elements were bypassed:
The new version is 120V for pump and controls and 240V 4.4 kW heater element with safety elements replaced:
The only thing left is to add labelling:
Long verson of the story:
The 8060A DMM was used in this project. You can see the RM564 in one of the photos; this Spa needs to be completed (among other things) before I can work on the RM564.
SWMBO found a cheap used Spa. It was actually fairly priced and a suitable type of spa for our property. Since I was already installing a free* used pool, adding this should not be a big deal (tm).
In reality, it has been a whole project unto itself.
Unfortunately, it became linked with building a deck during a lumber shortage.
Unfortunately, Murphy found plenty of opportunity.
- need to replace a cracked drain plug
- I now know where water
is most likely to WILL freeze in the pipes
- it needed 3 orders from DigiKey to get all the correct parts (with extras to get minimum orders for free shipping
)
SWMBO has also stated that it is required to have an alternate means of physical cleanliness (the spa) while I am doing renovations of the bathroom.
Renovations of the bathroom are required due to hard corrosive water corroding the plumbing fixtures; currently baths are prohibited and showers are worrisome (I have my work office directly below in the basement
)
