Would you happen to have a photo showing how and where you mounted the decoder and speaker?

I am just embarking on modifying a series of the Bachmann 0n30 trams.


Where did you obtain the sound file?

I haven't been able to find anything other than the Digitrax generic heritage streetcar?


Thanks David

I have a question too.

I'm about to DCC my first street car,
and I'm curious whether the headlamp resistors on the PCB can be reused in series with the LEDs,
or if I should get new ones?

Also, does it matter which end of the resistor faces the LED,
or does it absorb power both ways?

(I'm not too versed in electricity, sorry)

I am not an expert,
but I have never worried about which end of a resistor is the input end,
and I have never had any problems.

I don't see any reason why you shouldn't be able to reuse the resistor,
so long as the output from the decoder doesn't exceed the voltage the LED would normally get from the track.

I am replacing the LEDs with bi-colour ones,
so I have a red at the rear and white at the front.

The LEDs I have purchased come with a resistor,
I will check the rating of the existing and new and advise if they differ.

How did you get on?
I have been distracted with a group railway layout, so my trams and tram layout have seen little activity for a few months.
With the railway layout now ready for the scenic crew it's back to my trams.

Huw,


Do you have any photos to share of your exploits with the Bachmann 0n30 trams?

David,

No photos, I'm afraid. At the time I did anything with that tram, I didn't have a digital camera - but you haven't missed much.

If I recall correctly, I don't think I really did very much with the tram - add some prepainted figures - paint the window frames and bench seats - add a couple of stickers to represent notices - add a bit of thread to represent the rope used to move the trolley pole. In other words, the sort of stuff that wouldn't take anyone very long to do.

I certainly didn't do any DCC stuff - not much point really, when I'd have nowhere to run it.


More recently, my time has been pretty much taken over by looking after my parents - which is why I haven't had chance to do much in the way of modelmaking for some time. It's also why I haven't had chance to post on here for quite a while.

The posts I have had chance to put on a UK site have tended to be in odd seconds, snatched between being summoned to the opposite corner of the house to deal with "stuff" - either that, or posted well after midnight, when I've been so tired that I have difficulty even remembering my name. (This might also explain why my blue eyes have recently taken on a distinctly reddish tinge - but I digress.)


At various times, I have wondered about using Bachmann On30 trams as the basis for a number of decidedly "niche" projects (if I get the time, that is) - but they don't seem to be in the shops these days. The very few I have come across secondhand have been at "wishful thinking" prices (in this sense, a bit like OO gauge Lima / Hornby GWR Diesel railcars) - so the chances of me buying any of the things have been south of zero.

Similar comments also apply to Bachmann On30 coaches, combines etc.. That's right - I've wondered  about some "niche" builds using these, too - but I also don't expect any of these to see the light of day any time soon ... .


Of course, all this talk of "bashes", conversions etc., does assume the availability of time to actually do any of these builds - builds which would probably rely on "Rule 1" (it's mine - so I'll do exactly as I choose) and assumptions that the vehicles had lasted longer then been modified or cloned.

If I ever get the time to build any of these, I could see my plans changing - either that, or a long queue of potential builds, with loads of time wasted deciding which projects should be first to get built. I could imagine other people here facing similar dilemmas - for a variety of reasons - enough said, really.


Huw.

Huw,

I have a little more time on my hands for a week, before we have the next manic session.

I originally set out just to use a couple of these models with a narrow gauge railway layout, but as with so many things in this hobby things haven't worked out that way.

I am now looking to populate the whole of the narrow gauge section of a tram layout using these models.
first job is to lower the body which I have found is simpler than I thought it might be, then I looked at the track and because I plan to have some 3' 6" gauge trams I took the decision to re-gauge the models, which again is proving to be simpler than I anticipated, only made unsatisfying by the fact that I cant get the bachman wheels to go on to the new axles with out having some wobble.
I have also found a company in the US which makes a wee enclosure window frame for the balcony, they're not too expensive and look quite nice once fitted in place.

The next challenge is a bogie tram using two bodies, I haven't worked this out yet but the scratching of a few more grey cells should help.

The one thing I do need to sort out and haven't really give the attention it needs is the fitting of DCC decoders, granted it may seem a wee bit OTT to some but I want sound and lights that don't change their intensity depending on the speed (power supplied to the track) I am presently thinking about the digitrax decoder simply because it has two down loadable sound files but I am open to hear of other options people might be using.

Anyhow that's a very quick overview on my interest in these models.

David
