Bachmann J72


Recommended Posts

  • RMweb Gold

The J72’s had to be rewheeled owing to the wheels having too many spokes. It has lead to a few problems with running, but I can only say that my three are all very good, smooth runners indeed. All were tested in the shop prior to purchase.

 

Regards,

I wonder how many sales Heljan will loose with their - likely to be - F rating. 

Will we stop with our hobby or stop buying when other manufacturers also switch to coreless motors? I don't think so, Precisely because there are no worse results at DCC, and manufacturers are seeing increasing sales there. At the moment there is little difference in price with large numbers of motors they buy. (If they can still buy the old ones) However, this is now changing, making the choice for the MRR manufacturer.

 

You can always build large stocks of conventional motors so that you can move forward yourself for the next years.

When the old-fashioned light bulb went out, not everyone was happy either. Now we don't know any better.

I agree there. All these labels of 5-pole, coreless, 50/1 drives etc. while they might look nice in marketing, they are not really going to influence my purchase. What will is the choice of subject, my experience with the manufacturers models and feedback we see here. I'm sure Bachmann will have thoroughly tested these on DCC before manufacture unlike another make (now gone) whose coreless has proved a right cow on DCC.

 

Maybe these small coreless motors will consume less electricity but I do feel the bulk of the energy these models consume is when they are made and shipped halfway across the world. Once here, most will spend there time stuck in their boxes so any life long energy savings over an older 5-pole iron core motor are negated!

 

I found the idea slightly amusing in model trains having energy efficiency stickers like we see for fridges etc. The world might just be mad enough to do that 50 years from now.

Mine did 4 15 min laps of a Kato Oval yesterday- back, forward, turn round, back, forward to ensure even running in of everything but it was slightly noisy. Then put a non sound Zmo decoder in and having last decoder fitted a couple of Hornby models what a delight it was to have a loco on which the body just dropped off without a problem once the screws were undone and the loose wiring inside was pretty precision fitted. That was a distinct comparison to the appalling excess of wires resulting in a spiders web of them in the Hornby models which in one case posed problems refitting the body. The Next 18 socket seems to me to be simplest to fit a decoder in that has existed to date; no bent pin issues and 100% foolproof on which way round the decoder goes though the positioning of the socket in this loco.

Shows how good the old Mainline version was for something first made in the mid 1970s.

Absolutely. I was reckoning on retiring my Mainline one once I acquiring the new Bachmann version, but while there's more finesse to the new one and I love it to bits, the Mainline one still stands comparison and is more than good enough to shunt the Ministry of Munitions site.

Mind you, it hasn't stopped me buying 2313 [the LNER Newcastle pilot] as well, and for the record both of them run fine out of the box with no problems.

Hi Nathan70000,

 

If you are happy to replace the smokebox handles on the early one then you could pass it as one of the BR batch with relative ease.  The late crest model has, IIRC, both vacuum brake and steam heat;  I don't have access to my books to see if any of the 69xxx batch had those.  If you can wait a day or two then I can check.

 

Hope that's of use.

 

Regards,

 

Alex.

True, and there may also be the matter of buffers as these varied across batches and works visits.  I've just managed to get to my books so hopefully they'll have photos of the OP's preferred numbers; I can then compare them to the Baccy model.

NO PLACE now has an E1 with sound and a stay alive fitted by Digitrains.

 

It will nicely run into the siding that defeats so many other engines, and back out again.

 

 

Only downside is I bought it for the preservation side of the layout.  It could displace others from the colliery yard.  I'll have to get one of the Hornby WD saddletanks away for similar...
