Actually, It is not a matter of which technology is better. It is a pure marketing decision. Lionel IMHO really blew it with the introduction of Lionchief. First with having LC then implementing LC plus. So, really they created three distinct technologies. One remote only, one AC and remote and TMCC (AC and remote)
Why would someone design a system that does not allow upward mobility to your best remote? Why would someone design a system and within that system there are 2 types of engines LC and LC plus.
I'm no fan of MTH because of personal preference. But, they made the "RIGHT" decision with the starter sets with the cheap remotes and upward compatibility to DCS. Something , I'm sure the PROTO1 saga had something to do with that decision.
I was a broad base product buyer. I guess Lionel didn't heed...history's lessons.
Afraid I've been away from the forum and missed this thread as it was happening, though most of what there is to say I've already don on other threads regarding the technology in our hobby. anyway, in two parts:
Shawn, I actually think it was fantastic marketing. The LionChief system was never intended to be anything more than a starter set, and likely intended for the vast majority of the customer base where it will be the first, and likely, only lionel purchase they make. As a stand alone package the lionChief sets are really pretty great in what they offer, compared to the starter sets they replaced. Comparing a polar express LionChief set to the Legacy scale version is an exercise in futility. on the other hand comparing it to the same priced conventional set from a few years back you get a lot more 'play value' from the easy to use control and nice, if simple, sound set.
"Why would someone design a system that does not allow upward mobility to your best remote? Why would someone design a system and within that system there are 2 types of engines LC and LC plus."
This is one of those things that you have to look at from the business view. I douby anyone involved with the rollout of Lionchief foresaw the response and demand they got from folks that were not new to the hobby. LC+ was created by demand for just a little more functionality from folks used to cruise and electro-couplers. As far as marketing, when you already have a microprocessor and a radio link, the cost of adding the features of LC+ is almost nothing, so why not release a version that will make a larger segment of your costumer base happy. in the process you can phase out purely conventional locomotives as LC+ can be run as such. In effect rather than adding two new lines of product as you suggest, Lionel has simply replaced the conventional starter sets with LionChief, and replaced the better quality conventional locomotives with LC+.
For part two, the dreaded topic of the "technology" debate. Many here suggest that the radio and the actual guts of the engine are two separate things, and one should not be confused with the other. This is only true to a point where the radio becomes a limiting factor, or the hardware necessary to operate the radio that must be there anyway adds to the available technology. On the radio it's self, the 2.4Ghz off the shelf transceiver is vastly superior to the Tmcc/Legacy track signal. This is not just a case of newer/higher more dependable signal, but also the amount of data that can be sent and the bullet proof system used to send that data. these 2.4GHz units cost about a buck each in low quantity, and I would guess about 25-50 cents in the bulk orders used by a manufacturer. For that cost you an off the shelf, no coding on your time redundant, auto error correcting digital data transceiver. What that means is when you send data, the radio automatically checks to make sure it got the right information without wasting time on any of the other electronics. In lay terms, the analog signal in TMCC/Legacy is like watching someone choosing cards from deck over and over and holding them up for another person to see for only a moment, and another person finding that same card in another deck and setting it aside. From time to time, you're looking down to find a card and miss the next one shown, with no way to look back at it. On the other hand the digital signal used in the 2.4Ghz radios gets the same job done with the first person simply saying what card they want to the radio, and the second radio in the engine passing the second 'person' the desired card. Not only does this free up the electronics to do other things, but in addition the radios talk back and forth to each other Ex: Radio1 says "I need an 8 of clubs" Radio two then replies: " Did you say 8 of clubs?" and the first radio then replies : "Sure did", or if there was a mix up and the information doesn't match, it might reply " No, I said the 9 of spades, you deaf fool". Only after the radios have confirmed that the correct information was received is it passed on to the rest of the electronics package. In practical terms what this means if you never have the wrong command sent, and what's more, the radio will repeat the command if it was not received because of a bad signal. You don't have to press the button over and over, it will do it for you.
The other side of the radio tech is the massive amount of data that can be sent. Tmcc uses two bytes of actual data to preform every possible action in the system. That is equal to having 16 light switches that can be on or off. Legacy improved on the system by adding one more byte of data, or 8 more switches for a total of 24, though in practice they only use 2 of the added bits, or "light switches". Legacy does allow "multi-word" commands but these are only used in a very few cases. The radios that are already in LionChief and LC+ engines and remotes, on the other hand can send 32 bytes of data at a time, or 256 light switches, to keep with the analogy. When you consider what adding 8 bits to tmcc did for legacy, there is no practical limit to what could be done making use of these radios as far as the functions that could be controlled.
All in all I think anyone should be able to agree that the radio technology in LC is vastly superior to that in TMCC/Legacy. So what about everything else, the so called electronics package that the radios are talking to? Well if you have a micro-controler in your engine that is capable of reading the serial data that the 2.4GHz radios provide, it also already has several digital I/O pins. I don't know what processor they use in Lionchief or of they use the same one for LC+ but I do know that the cost is about $1.50 for one that could easily run any legacy locomotive, so the cost of adding capability is not particularly much if the processor being used is not powerful enough. Your basic $1.50 micro-processor these days could control about 12 functions on it's own, but the neat thing is, each of those pins could be programed to control another chip turning it into 8-16 channels. What this means in terms of 'what technology is better" is that theLion chief and Legacy, from an electronics stand point are already exactly the same level. One just has a few more parts on the board to allow it to take advantage of the full power (actually still a small percentage, just more than LC+) of the micro-processor. The only difference in technology between what makes an LC+ work and a Legacy work is the number of output channels connected to the micro-controller the rest is all physical hardware, such as a better sound chip that allows sounds to be mixed, a few more LED's, and that's really about it.
The thing I find interesting in all this is that it would be absurdly easy for Lionel to make a box that plugs into the serial of a legacy base that would allow the legacy remote to operate Lionchief/+ locomotives. It would also be insanely simple to produce replacement boards for the R2LC/legacy equivalent that use the 2.4ghz radio and elimante the track signal problem. Why is this unlikely to ever be done? simple, coming out and saying your flagship, top end electronics package was out-dated tech the day it came out and garbage now is no way to run a successful business, and it's better to let people think that because one currently has more features it must mean the other can not do the same thing. No one needs to know that under the hood someone pulled off half the spark plug wires on LC to keep it dumbed down at the upper entry level price point.
On the other side of that, if MTH's next system used these bullet proof radios in their next system they would instantly remove the need for PITA star wiring and give buyers all the functions they currently love in DCS with out any of the drawbacks.
