A&O Operations / Guest operators from Tulsa and KC
« Last post by Bob on April 02, 2025, 02:39:39 PM »
On March 31st the A&O hosted a morning + afternoon op session for an entourage of experienced operators from Tulsa and Kansas City. A contingent of A&O regulars also attended as consultants. Special thanks to KT for a fabulous lunch.

Sorry I don't have names for all these faces, but here are the few photos I managed to take during the session. And remember that if you want to see a closeup of any photo thumbnail, just click on it to zoom in.

Jared held down the Dispatchers's desk. I trained him on the peculiarities of the A&O machine and he did a fantastic job.


Here are more grab shots in no particular order.

An empty coal train headed north across the Twin Creek Viaduct. Soon an impromptu photo line of folks stacked up. These locomotives built from P&D kits appeared on the cover of a 2006 issue of Model Railroader. Each currently has a 2" high-bass speaker in an enclosure.

On the distant right the Grand Floridian passenger train would soon pass over the Ohio River on the connecting bridge.


I overheard several comments about the sound coming from the "giant speakers" in A&O locomotives.

The Floridian soon crossed the Ohio River behind two of David's Atlas F3s. These sport Tang Band T1-2025 speaker modules that produce a lot of bass due to their large passive radiators.


A general freight heads from West Virginia to Ohio as it starts across the Ohio River bridge complex behind Alco C425 #475. The dynamic brakes would soon whine to take the train down the ruling grade towards Millport OH.



A loaded coal train just arrived at the Hatfield Coal Company rotary. Here an operator pulls off the caboose and parks it safely on the caboose arrival track.  Soon the loads will be pulled off the tail of the arriving train and shoved across the Whiting Rotaside for emptying. These are all live loads.

The rotary is controlled using the green circled pushbutton visible on the fascia. Once started the dump cycle runs automatically and is synchronized with sound recorded from a real Whiting Rotaside dumper.


Here's the road power, an Alco FA1-FB1-FA1 consist that brought the loads to the rotary arrival track.


Later the B&O ran north on the A&0 mainline to exchange a few cars at International Paper, then it headed into Millport for the midpoint of that turn.



Millport yardmaster Craig herded cats.


What hump?


Heading to the home terminal past the end of CTC.


Operating at the Morrison prep plant. Dirty coal in, clean coal out.


John Parker held down the Ricksburg yard job. Here he answers the Dispatcher on the telephone system.


Ricksburg sorts through car cards to plan his next moves with the Alco S4 yard switcher far left.


An aging Alco RS36 switched the 28 foot long paper mill. That job can take all day! (I've been there and done that job...)

Awesome wife Katie figured out the magic words for putting up the video shorts. Enjoy. More to come.

Greetings-
It has been a long time since I was able to update the A&O website, but that has just been accomplished! Yeah!! I hope to not be so delinquent going forward; we'll see.
There are new categories added and probably an overabundance of data.
If we can figure how to do it, some video shorts will be posted on the Photo page.
Enjoy,
David Stewart

Hello and Happy New Year !
At noon on Newyear MTSE steam engines joined the whistle up to welcome 200 years of railway in the UK

Very nice, Michael. You have captured the essence of prototype operations on your beautiful railroad. Great fun! I hope others in Deutschland enjoy it with you.

I so wish I had been home when you and your son Toby came by to visit the A&O, such as it is at this point. If I ever get back to Hamburg I'll let you know.

Hello,
my MTSE, narrow gauge railroad according prototype RüKB on German Island Rügen, operates strictly according " Zugleitbetrieb" which is quite similar to timetable and track warrant. If you are interested how I implemented it follow this link: https://www.0e-club-hamburg.de/mtse-michael/mtse-betrieb/
Unfortunately in German only, but google translator should work fine.

Hello,
meanwhile my second layout, transportabel for exhibitions, is in a good stage to look at.
It consist of rolling stock according prototype of the Mansfeld Copper Mining Railway located in east Germany, but on an freelance layout. Most of the rolling stock still exist at todays museum raiway MBB in Klostermansfeld.
Please follow this link: https://www.0e-club-hamburg.de/mansfeld-michael/
Unfortunately in German only, but google translator should work fine.

A&O Operations / Re: Visitors from Germany
« Last post by MichaelHH on December 02, 2024, 08:19:14 AM »
It was really a great pleasure for us to visit and oprerate A&O Railroad. It will stay for long in our memories.
Thanks again to Dave and Bob for making it possible.
It is realy very sad that the distance between Hamburg and A&O is so big. I would love to regular join operation sessions.
I wish you all the best to keep everything rolling.
Greetings from Hamburg

After assembling one of the lighting blocks I quickly realized that having so many loose wires coming out of the back was not going to be fun to solder to a small prototyping "relay" board on which the dropping resistors were mounted. For one locomotive that might be OK. But I have a bunch of GP9s to build and David has a small fleet. Hmm... back to the drawing board?




While feeling frustrated I saw a post by Mike DeBerg on O Gauge Railroading showing the interior of his new 2 Rail SD40-2 from Sunset. That was the cleanest DCC install I've seen.
https://ogrforum.com/topic/sunset-models-3rd-rail-sd40-2-an-inside-look

Sunset designed a new daughter board for the ESU 5L decoder. That custom board uses a bunch of JST XH connectors for wire management. A real incandescent light bulb turned on in my head... Why not have some custom PC boards made that could attach to the back of a lighting block?

From US vendors prototype quantities of PC boards can be quite expensive. Many 3D printing channels on Youtube are sponsored by a Chinese company out of Hong Kong, JLC PCB. I uploaded Gerber files from KiCad and got a quote for only $2 for 30 boards, including a $6 new customer discount. Including shipping the cost per board was less than $1.

I downloaded the current (and free!) KiCad software for schematic capture and PC board layout. It did not take long to arrive at a PC board design. That said, soldering the LEDs to the board would require reflow soldering, something I've never done at home.


The lighting block was also modified to have open apertures for PC mounted LEDs. The two central mounting holes are sized for M2 threaded inserts.


Soldering tiny wires to the back of many surface mounted LEDs is not all that difficult. But how can one solder the LED to a PC board when the contacts are hidden on the bottom of the package?  That requires reflow soldering, in which a paste of solder and flux is applied to the PC board pads and the LEDs are set into the paste. Then the entire assembly either goes into a reflow oven (at a commercial facility) or at home on top of an inexpensive digitally controlled hot plate.

I bought a cheap digital hot plate from Amazon and in an afternoon reflow soldered 5 LEDs to each of the 30 prototype boards.

Here are a sample of the results. On the left, one of the reflow boards with 5 SMT LEDs. Center, a modified lighting block with clear apertures for LEDs mounted to the PC board. Right, the back of the PC board with a pair of JST connectors. The upper one connects back to the decoder board. The lower connector powers ground (truck) lights, if used.
