I don't know what an FP7 is supposed to sound like, but it can't be this. When I first put this thing on the rails I thought maybe I'd accidentally received a non-decoder version because the sound it makes when sitting there idling is very much like the whiny racket a DC locomotive makes when sitting on AC rails. Talk about underwhelming.

Also, it looks like Ajin has gone bye-bye. These are made in China now.

Do you still have it?  Assuming that you haven't successfully run it under DC and DCC, can you peek inside the shell? What is in there?

Yes, I still have it (haven't finished testing it yet). It runs fine, it just doesn't sound very good.

Internally it's basically the same as the previous Model Power / Ajin "Hobbyist" version. Apart from the new LED headlight board and the sound decoder (wired up and elegantly insulated with scotch tape), the only other difference is that the couplers have been changed from Rapidos to E-Z Mates (the same ones Bachmann uses).

P.S. If you want to take it off my hands, it's all yours  :D

No thanks Mark, I think that I'll pass on this "gem".  :D

So does it actually make sounds other than the nasty sound you described above?  Horns, bell, "real" motor sound? Or should I just wait for your complete review?  That speaker doesn't seem to be in any sort of a enclosure - that in itself will result in a very poor sound.  Who designs these things?  Do they have any clue?

Perhaps I wasn't clear - the nasty noise I described earlier *is* the diesel motor sound (I just didn't recognize it as such right away). And yes, it has all the other typical sound features. But like the diesel motor sound, they're all just very thin and tinny sounding (no doubt due, as you point out, to the lack of any sort of speaker enclosure). Making matters worse, the loco itself isn't a particularly quiet runner and so basically drowns itself out. All in all, this may be the worst implementation of DCC-Sound I've ever encountered.

Apparently not :facepalm:

 :facepalm: :facepalm: I guess my brain did not want to accept what was implied in your earlier post.  Then the photo you posted later showed the reason: tiny free-standing speaker. :facepalm:  :facepalm:
And yes, with that tiny and enclosure-less speaker the sound quality of the motor (or any sound which depends on lower frequencies) will be extremely poor.

As cjm413 correctly indicates, on All Tramps Sent Free EMD F-units, only the Bs had steam generators. This seems to have been a practice peculiar to ATSF, as I am not aware on any other roads that did them that way.  I wonder if it was a holdover from the passenger FTs, which had room only in the B-unit for a steam generator.  (another peculiarity of FTs was that the batteries were jammed into the smaller A unit, despite there being more room for them in the B)

B&O did have some dual service F-3s that it ordered as A-A pairs from EMD:  one had the steam generator and small water tanks, the other one had extra water tanks.  Of course, as the passenger trains disappeared, the railroad did break up the pairs.

I was not aware that Sudden Pathetic had regular F-7As with steam generators.  They must not have worked the SF Peninsula.  SSWs FP-7 did, and it was on its last leg when I rode behind it in high school.  It often worked #110, which was usually only a single Harriman sub (the mail and express traffic that it carried when it initially was carded in the late nineteenth century had disappeared by the mid-1960s).  If you had to be at Bellarmine or St. Francis for an activity before school you rode that one instead of #112, which was the "Schoolbus on Rails", and got you there just before home room.  I do not recall seeing those other F-7s with steam generators on either freight or passenger trains on the SF Peninsula.

The freights got a mixed bag of power, but mostly EMDs.  Most of the yard goats were FMs.  GP-9s usually powered the local freights.  Occasionally, an RSD-4 would show up in Santa Clara Yards (I saw the crew fire off one of those one time while I was waiting for a train at Santa Clara.  These flames shot from the exhaust stack then a thick cloud of black smoke everywhere.....................)

The Daylight, by that time, usually had E-units.  The Del Monte usually had a pair of torpedo boat GP-9s (although some times it had one or two with dynamic brakes and a steam generator).  Weekdays, the commutes were mostly Trainmasters; weekends "Cadillacs" (SD-7 or SD-9) and GP-9s.  I do not recall ever seeing a regular F-7 with a steam generator there, though.

brokemoto -- you are correct about the Espee -- their F3 and F7 "A" units did not have steam generators. However, they did have a couple of series of F-7B's that had them as well as (of course) their FP-7's.

Is it still available?

I do not recall seeing F-7Bs on the SF Peninsula that had steam generators; perhaps they worked somewhere else on the SP.

The freights to and from San Francisco often had F-Units, as well as other power.  Anything heading East from San Francisco usually crossed the Dumbarton bridge, which meant that it had to change train numbers three times.  It was railroad East from San Francisco, then railroad West toward Oakland, finally, railroad East away from Oakland.  We did not get too many eastbounds as far south as Palo Alto or San Jose, unless there was congestion around the Dumbarton Bridge and they were going to head south, go through Santa Clara then head north up the East Bay.  We did, of course, get the SF-Los Angeles freights.  Often, they stopped at Santa Clara Yards to have cars added.  Often, there were F-units, but not always.  The long distance freights were almost all EMD powered.
