New 47s... any issues?

If anyone is contemplating buying one of the new 47s you might want to ask for a test run first. The first one I looked at in the shop stuttered, the second was very noisy and the third was okay and I bought it. I may have been unlucky with the first two but that is a bit worrying... 

 

At £134 one should expect top quality running without issues. One always wonders how many get returned?

You used to need to run them in. It helps distribute any lubrication and seat the gears and brushes. I've found that, especially for Farish, it also helps wear the blacking on the treads and where the pick-ups rub to improve conductivity and running smoothness.

 

Do the instructions still advise running-in?

I've had a few of the 'new' 47s over the years. The only real pickup issues I've encountered has been with the way contact is made between the various surfaces as power passes from the wheels up to the PCB and on to the motor. There is no soldered wire connection, the path provided for current is via several sprung contacts, which generally speaking is good enough to do the job. I have had to strip models down to clean excess oil/grease which has found its way into the pickup system though. These have mostly been second hand models, but my very first class 47 of this type (Titan) had these contacts literally filled with the factory lubricant/packing grease and would barely run from new. Cleaned up and lubed properly it ran flawlessly before the wheel blackening had chance to wear down, so I'm not entirely sure that the wheel blackening should be that much of an issue; it certainly is an issue for lighter models with fewer wheels, but it should be a minimal problem for something larger like this.

I'm not so sure that the white packing/transit grease that is often found caked in on Farish models is meant as a lubricant - what is recommended by Bachmann for lubrication is far less viscous oils. I usually pick and scrape out the grease - not that it's easy to completely clean out - as it seems to add drag.

 

But I have found that generally performance improves with appropriate running-in. And that with use the blacking does wear.

Bachmann have published/stated return rates for Farish in the past which are significantly lower that many assume. And presumably they find that level acceptable, although, no doubt, would be happier to see it reduce.

Yes I suspect the transit grease is the main culprit. I have cleaned it off a couple of locos I bought unseen second hand and it can certainly be a factor in poor running. 

 

Running in is still recommended. Over the years I have found this makes a difference to some models but not others. Obviously much depends on what the problem is in the first place. Personally I won't buy now unless they run almost perfectly at the point of sale.

I've noticed that many retailers who have photographed the models seem to show the LEDs sticking out a bit. Looked odd to me. Thankfully the ones I want are not out yet. Fingers crossed.

Yes they are more prominent and not as good as previous releases. I decided I could live with them but no doubt some people will try to recess them or look for alternative flatter LEDs.

Ive had a couple of farish 47s and theyve always run smoothly, only slight niggle is sometimes the rapido can catch on the large oleo buffers.  I fancy the railfreight grey one, it looks like the bulbous marker lights on latest batch are only on one end and can simply pushed in, has anyone tried?

I've recently bought 371-249  Class 47/0 47018 in large logo grey. It's only had a test run so far but no sign of excess noise or poor running - every bit as good as the other class 47s I have.

 

 

Steven B.

Likewise the large logo one I have.

I have had four new tooling 47's.  The Titan and green 47522 ex set one have run like a dream, a second hand one I acquired was a total bag of spanners and the ScotRail 47/7 refuses to go round left hand corners....

I had one a few years ago that didn't like corners. It turned out to be misaligned pick ups that were acting as brakes at slow speeds. Pick up problems were quite common on one batch - they had been assembled incorrectly. Another possibility is split gears, although these are rarer now.

I have a handful of Farish 47s that prefer corners to straight sections!

Dear all,

 

I’ve recently been given a farish 47 for my son’s n gauge railway and one of the gear trains is binding every revolution.  Any suggestions on a way forward - it’s way out of warranty...

 

Here is the troublesome gear tower:

I've got a few 47's from Farish, all bought new and every single one of them was smothered in oil from the factory.

 

47535 managed to split 5 out of 6 axle gears.

 

Apart from that they are all good runners..

 

Cheers

Mark

I've just got two duffs bought new 2 to 4 years ago. Both very good runners. Smooth quiet and pull well. I always give locos a good run in. I keep oiling to just one drop per axle and not too often. Over oiling is quite probably the main cause for faults on N gauge locos. I managed to over oil a couple of locos, they started to run badly so I oiled them a bit more. This was a stupid thing to do and I ended up stripping them down and cleaning all the axles, bearings gears etc.. It does seem to me that the more regularly N gauge locos are used the better they run. 

 

I was told a couple of years back that the return rate for both Farish and Dapol is around 5%. In conversation with someone who used to repair Bachmann locos a while ago he reckoned that a lot of the returns were due to misuse/owner error rather than a fault on the model. I also heard that if they are aware of a problem across a batch of locos Bachmann will fix the whole batch before sending them out to shops but this is extremely rare.
