I read this thread with great interest. I purchase a lot of non-powered units and was disappointed that MTH has not cataloged non-powered Premier units in the last two catalogs. They discontinued them earlier in the Railking line, though I think that they had a few in the just released catalog.
Non-powered units solve a lot of problems and fill many needs on my layout:
1. I'm not a big user of DCS (a discussion for ANOTHER post) so non powered units allow me to build consists of TMCC or Legacy equipped engines with MTH non-powered units
2. Two powered units of any manufacture (and pretty much a single Atlas unit) can pull anything I throw at them on my layout. And I run long trains...typically at least 27 40' cars. The non-powered units let me run impressive looking diesel consists of three and four units without the expense and upkeep of all those powered units
3. It also overcomes the issue of similar TMCC and Legacy units which run poorly together as they run at different speeds (Example: the TMCC PRR and Legacy PRR RS-11's don't run well together)
4. You can easily introduce foreign road power into a consist of engines (which occurs all the time on the prototype today) without the expense of a yet another powered engine and the aforementioned compatibility issues.
I spoke with Rich Foster of MTH about this and he gave two reasons for them discontinuing the non-powered units. First, the cost kept rising, and he felt many people would not pay roughly $200 or so for a non-powered unit. Secondly, he said they would sometimes order as few as 30 or so non-powered units from the factory and the factory would grumble about manufacturing this low number of pieces.
I know some people state they won't spend the money on a non-powered unit. This is a matter of personal opinion. I obviously will do so, and when you start buying 4-6 or more dummy units a year, the roughly $200 differential between a powered and non-powered unit really starts to add up.
I think comments made on this forum in part have helped to drive up the cost of MTH non-powered units as well. There were repeated requests on here for lighted dummy units to which MTH finally responded. I think part of the assumption was that "what the heck, its only a pickup roller, two sockets and bulbs, it'll only cost 10 bucks or so". The reality is that MTH included a constant voltage lighting circuit, and the actual price increase was about $35. I personally never saw the need for a lighted non-powered unit as on the protoype, only the lead unit is lit.
In any case, I did point out to Rich that some Lionel non-powered units are listing for around $260 (see the SP SD-40-2T in the latest Lionel catalog) so at a MSRP of $200 for an MTH unit, they are still competitive pricewise.
Anyhow, that's my take on it. Rich pretty much indicated that he would reconsider if he received enough demand for non-powered units. So if you want to see MTH resume making non-powered units, get in touch with them and let them know. Heck, make life easy on yourself...just print up this thread, write something to the effect of "I agree" on the top, and throw it in the mail.
