Nice introduction to RFID on model railroad!!! My overall block detection will likely be IR proximity sensors because of cost and they detect anything easily. But to detect a specific engine or piece of rolling stock the RFID might be the way to go. You're idea for updating an OLED station train board would be fun ... Cheers!!!

This is super awsome. RFID or NFC. With this technology we can track where the certain train it is. And at what time have pased in that point or arrived at station. And at same time can make automation runs opens close departure. i like its working. Now i want to acomodate it right betwen rails not under. Like the decoplers in the midle of the track.

Always something interesting from your presentations. If I were doing the RFID sensing I would use i2c and a multiplexer to read from multiple sensors (Adafruit TCA9548A). The RFID readers interfere with eachother if placed too close, so I would use the point selection to determine which sensor should be powered. I have built a demonstrator that used multiple RFID readers and we had to cycle through them powering them individually.

Very useful, I’ve gone down a blind ally with tracking. I used BDL168 wit RX4s. At first I thought it was reporting transponding, turned out my decoders weren’t doing it, it came from the DCC command station! Even saw locos in the memory of the DCC that were still in a box! Need a plan B.

Does Grove make an RFID reader that can read at 13.56 MHZ as it seem to work better at operating speeds ? Any follow up on this ? Can two tags per engine be used to determine direction ? what about using a loconet shield on an Arduino to mimic an alternative to transponding using RFID. Connecting multiple hubs via ethernet (best for speed ) or mqtt or usb multiple ports which is best ?

very nice intro, I've not tried it but I did wonder on this sort of thing. I was considering it as something to use in a few spot locations to work with control logic - e.g. exit of some sidings to confirm what train actually left a given road (with tag under locomotives) then *hopefully* the system can keep track of that as it goes block to block. I.e. not using them in every block, just occasionally at points most trains cover. Also as "decision points", say on the approach to a fiddle yard to enable intelligent routing of trains. its certainly very interesting though and this intro shows its actually a lot easier than some others have made it seem. Interested so see more experiments :) Also suspect I2C is useful for multiple sensors on one arduino. the uart serial stuff a bit more restricted unless the sensor has some sort of interrupt output but even then awkward - there are controllers with multiple uarts though

Hi Rob. I appreciate your material very much. Unfortunately this Seeedstudio Grove 125kHz RFID Reader is not available in Brazil (importation tax are very high in Brazil). I bought an 125 kHz RFID Reader (RDM6300) but it didn't work in any protocol available in JMRI. Have you tested some similar hardware? I hope a JMRI update that supports another popular RFIDs like RFID RC522 or RDM6300 plenty available and low cost hardware. Thx.

This might be a case of analysis paralysis Rob but might it be worth planning what you want to to and building it as part of the original build? Might be more difficult to retrofit it. I'm considering something like this for my planned layout which is intended to be an exchange yard offering lots of shunting with wagons heading to multiple destinations. I'm not sure using RFID for block detection is the way to go - as you say it detects in a single spot. I'm guessing you would want multiple RFID tags in a JMRI block and automation relying upon RFID for indicating a block is occupied would possibly prevent more than one tag in a block. Love the video though. It's so encouraging to see how easy this was to set up.

The 125kHz tags won't work under the baseboard. The range on a 125kHz tag is roughly under 2cm. The problem is that range is slightly reduced when you introduce a baseboard, ballast, sleepers and track. You also have to factor in the distance on the rolling stock (wheel height etc) to where you put the tag. So it worked OK on your test because you had it under the sleepers and it could easily read the tag. Move the reader under the baseboard and it won't work very well. The best option is to use MFRC522 13.56MHz tags. These work really well, but the code required is a little bit more complex. My test setup for this is an 8 car HST set, you have to get really creative to capture all 8 RFID tags at speed in a block, otherwise you could misidentify or miss a coach, which is obviously not what you want :)

@Oorail

@@christopherdavis5544 Did you test this in rolling stock, or did you just test it sitting on track with the reader under the baseboard? The reason I ask is that 125kHz has a limit of 2cm, looks like those tags are industrial, so you might get a little more out of it. If you put the tag on the underside of a brake van, on code 100 track, its going to be 2cm from the top of the baseboard, further if you've used cork or some kind of underlay. The readers aren't flush with the bottom of the board either, at a minimum you are adding 1-2mm distance with the reader. So 20mm + 9mm + 1mm = 30mm, this is an entire cm over the spec before you even add RF interference from powered track, and the metal on the track. What reader are you using and do you have a demo of it working? If you just tested it above the baseboard, then that would probably work because 9mm + track height is still going to be within the 2cm. When you add movement, the height from the tag to the track etc, anything within spec isn't going to work right. That said, some manufacturers don't always follow the spec, so I'd be interested in finding out more about your setup as you might have found a combination thats just enough over spec to work :)

i guess another question is can you use a mix of RFID detectors and say current detectors for block detection, my own layout is based on a mainly single track prototype but it's unusual in that you can have multiple trains following each other even ending up with two or three short trains on the same platform at the same time it would be nice to be able to watch train a followed by b and c proceed around the JMRI screen but I am going to assume that this might only be possible if every block has a RFID detector which could rapidly get very expensive

Definitely keep the block occupancy current sensor. The RFID readers are a bit like IR sensors, only shows that a train is in one place. It's possible to do automation with entry exit sensors, but I think a combo of block occupancy and position sensors is required for confidence in automation.
