Source For Latest TMCC O-72 WYE Switch?

You can update a remote non tmcc switch with the ERR update to command.

I'm not sure what the difference is between the 6-81954 and 6-16832; both are CC and 6-16832 is available.  Remember, you will need 2 072 half curves to bring the tracks back to parallel.

Didn't Lionel add some type switch position indication for LCS? Could that be the difference?

Based on another forum post that mentioned the 6-81954 as the correct switch for this MTH train shed and included a picture of the switch to demonstrate the spacing achieved (after the 2 072 half curves added) I assumed this 6-81954 switch was already available.  I looked at the Lionel shipping schedule and could find no mention of 6-81954 there so this seemed to further validate my belief the 6-81954 switch was already made.  

However, most of the train shops I've called have either said the 6-81954 wasn't in their system AT ALL - meaning it wasn't just out of stock but had never existed - or that they showed the part number but it hadn't been made yet.  (Which in the end basically means the same thing either way.)   

So I'm now confused why it appears the 6-81954 has never been made while still not even showing up on the Lionel shipping schedule at all.  I wonder if they now have no intention of making it?   Many places seem to have the 6-16832 still in stock.  I bet they don't get a LOT of demand for them.  Perhaps they have taken the position that they'll only order the 6-81954 once their 6-16832 stock runs out - essentially creating a bottle neck.  

I think you are right, RTR12, but it doesn't say that on the Lionel site.

MOPAC01, since this is in the 2016-2017 catalog AND it is not on the shipping schedule yet, I think you may have to wait until sometime next year.

There's some thinking that the later version (which is not out yet?) will broadcast the state of the switch. Up to now, an ST2 is required to be connected from the switch controller LED signal. And the ST2 sends data to the LCS app. Thru wires.

Unless it's wireless, I don't see the benefit.

Perhaps a call to Lionel's Customer Service will answer your questions.

The 6-16832 O72 Wye is a command only switch. A remote controller is not included. It will indeed work with TMCC/Legacy and the LCS system.

Also, adding the ERR to a remote only version will work with LCS. The switch will still have an SW#? ID that the base will have stored and communicate to the LCS Wi-Fi.

MOPAC01 - put a couple of straights into the shed and measure the center to center rail spacing. It should be 5.25"- 5.375" on the top and center of the rail head.

I am confident that this configuration should fit. I just proofed it in RR-Track, where there is an shed to add to the plan. If it needs 5 1/2" inches let me know. I'll adjust the small tracks coming from the Wye ends.

This exact discussion took place in another thread some time back.

I just picked up a 2 stall MTH train shed for my son's carpet central.  Based on other threads on the forum, I need a 6-81954 fastrack O-72 WYE switch to make the split for the 2 stalls.  Earlier versions of this switch won't work because we're using LCS wifi and the LCS iPad app.  But I can't find this switch anywhere - local, online or out of state.

Anyone aware of some place with these still in stock?

There is no difference between 6-16832 and 6-81954.  They are both CC and also both have remote controllers included.  The 6-81954 is just the new item number when Lionel moved all their Fastrack switches to include both CC and Remote control.  Previously there were 2 numbers one with and one without CC.  Now they have combined them into 1 and actually lowered the price a bit.  So both above are identical except for the number.

All Fastrack switches (old or new number) require the STM2 module if you want to see the switch position updated on the ipad  IF  the switch change was done either manually or by the auto derail feature.  If a switch change was done by CC then the ipad position will be displayed correctly.

There is no difference between the switches.  They list both in catalog because they still have lots of the old stock to get rid of, but eventually there will just be the one number.  They consolidated the product so they can just make one switch that you can use manually, by remote control or by CC.  They new switches do NOT have any other features that the old numbers don't.

Don't listen to all the people on here who don't even have these switches and have no idea what they are talking about.  I have 25 Fastrack CC switches on my layout of both the old and new numbers.  There is no difference except the number on the box.

I have a 6-16832 on my layout going into the MTH double stall shed.  All I needed were two -072 half curves off the switch and the 2 straights then lined up perfectly to the shed as you can see below.

I'd already identified them via Google and phoned them yesterday.  Their webpage is inaccurate.  They do NOT have the 6-81954 in stock.

I've just gotten off the phone with Lionel and they indicate the 6-81954 has NEVER been made.  It's SCHEDULED to be made, but not yet on the shipping schedule.  Soooooooo, that sounds like *sometime* next year.   I was told the parts are nearly identical but they weren't exactly.  I don't know what might be different.   

At this point my son seems to operate much more with the wired remote throw lever on his existing 0-36 switches (which are of the newest vintage and have both CC, remote wired switches and manual throw) than with his Cab-1.  But he has asked about the LCS iPad app that he's seen me using.  So I really do want both the wired remote and the ability to use Cab1/Cab2 and the LCS iPad app.   These aren't inexpensive switches, and there aren't *that* many uses in a small carpet railroad for O-72 WYEs - so I only want to buy this once. 

I would think that the appropriate action would be to ask Lionel if the 6-16832 will work with LCS. I found nothing in the LCS documentation to suggest that special switches are necessary. Where did that information come from?

While I couldn't find any docs on the 6-81954, I did find them on the O-36 version, 6-81946. New and old manuals attached for your reference. They are virtually identical.

The only issue is that LCS only shows the state of the switch when you use LCS or the control to switch it. If the anti derailing function actuates the switch, then the LCS app will not show it. The question is, do the newest switches somehow allow LCS to see the setting of the switch in all cases without resorting to the SC2 device.

I don't think any of the Fastrack switches will reflect their actual positions without use of the SC2.  You can see the last commanded position, but the non-derailing function or a manual change will not be reflected.  The Fastrack command switches have no provision to communicate back to the LCS system, and I can't imagine any simple way to add to the electronics and make that happen.  The LCS depends on it's information coming across the serial link from various LCS components.

I have often wondered if Lionel will ever use the Data terminal on the switches, perhaps to connect to the LCS someday?

As I said above the newest switches do NOT have any other features the old ones do not.

The only newest numbered switch not yet made is the WYE.  But the other turnouts have been shipped and I have both old number and new numbers.  They are identical in features. 

Waiting for the new numbered WYE won't get you anything additional. 

Like I said its a consolidation effort for products.  Previously they had 3 different product #'s each at a different price.  Manual, Remote and Command Control.   Now its just one product# that contains all 3 options at a better price.   They made a mistake in my opinion listing both in the catalog, but its a transition so they had to because they still have old product# to sell and some new product# like the WYE hadn't been produced yet so they have to keep the old WYE product # in there too.

Just buy the 6-16832.  ALL Command switches work with LCS, there is no special command type switch to work with LCS.  I have a complete LCS layout.
