Finally got round to testing the one I bought at Warley and yet again the front directional lighting does not work at one end. Just my luck.. I wouldn't normally mind but at £118.95, looks like a trip to Cheltenham is going to happen  :'(
The headcode lights didn't work on one end of mine on arrival. A little wiggling to reseat the body on the chassis got it working in a few seconds.

Ah! So many things that can go wrong. I've got a 40 w/ sound on pre-order, and I'm scared to death that it will traverse the "pond" only to be dead on arrival.

It is fun this ! The dapol way has mini plugs that are a problem when popping the lid! And the fit of the lid and its pressure on the tabs the Farish way means a bit of play to coax into life. We cannot complain three much as we wanted light,sound and action ....
Hattons note my banger blue on its way - soon to be grimed and faded, hopefully I can convince the girl to go 2mmfs with wheels in stock.

cheers

hi everyone

i've just been playing with my new class 40....  now moved on to look at the detailing bits...

does anyone know when the multiple working was removed from 40159?

also what about the port covers for the boiler exhaust?

i'm guessing that if i want it to be 1981-withdrawal in 1982 i need to leave the multiple working cables off and put the exhaust covers on but just want to check this out before i start....


cheers

I'm not too happy about the white or silver handrails on the front of D369 which make them look overscale. All the photos I've seen of green 40s show these as green. Any views?

Heyday of the class 40s by Gavin Morrison has this loco with white handrails on the front cover

Also this pic top left on this page seems to show white handrails. https://goo.gl/images/aFkTQ4

Hi Everyone,

I'm drooling for the new sound one #40141 which is the only one not released. It says due October-November 2017 but still is not out, I think on the Bachmann website it says quiet a while away yet. Is it worth Pre-ordering it?

Regards Connor

Bachamnn wedsbite says December/January now, I would say so the video is awesome and I don't think any in the shops will hang around long.

 :hellosign: just received my 40159 today.

As others have commented superb model, ran straight out of box with all directional lights working and no jerking.

However my question is do they run a bit slower than other Farish designs, are they lower geared or is the added drag of a longer bogie and extra axle playing a part.

Ran in as per instruction sheet on Kato test track, dog bone shape, generous curves with super elevated cant, 414mm radius so way above minimum, powered using conventional DC controller by Gaugemaster - no feedback version.

Running in at 50% the loco was quite slow in comparison to other recent new purchases, 37 and 60 - never the less ran in both directions - no jerkiness.

Once run in did a comparative test on the test track which is just shy of a 6m run using a rake of 8 new type mark 1's

40159 at 50% throttle took 74 seconds to do one loop, 60057 (T/G Coal) - 34 seconds and 37422 (Regional Railways) - 26 seconds

Reset to 80% throttle; 40159 - 24 seconds, 60057 - 18 seconds and 37422 - 15 seconds

If my math is right the 40 does top out at a scale 85mph the others are obviously geared to run over scale maximums.

My test suggests that the model I have runs significantly slower at lower throttle settings i.e. 50% a long way off the pace, then closes the gap at 80%, but still significantly slower than the 37 & 60.

Has anyone else noticed this or is this a quirk of my particular model - as said lights wise and smoothness are A1 so don't want to send it back if this is how they are.

40s were not in the Deltic class for speed, so I'd be happy with 85. Wasn't their max 90?

I've bought two.  They both run the same, definitely a slower top speed than previous offerings.
Are they not the first diesels to have the new coreless motor?  Is this what is making the difference rather than gearing issues?

I agree regarding speed. Both of mine run slowly on the running in track. I thought the tight radius curves might have something to do with it, but apparently not!

I'm currently having a real struggle to get the body off the blue one to put a decoder in. The green one was bad enough, but this one just will not budge.

Based on Railbank's figures the top speed is more or less correct but the throttle response is markedly non-linear, delivering a scale 27mph at 50% throttle but 85mph at 100%.

That's curious as this (presumably DC) performance resembles that of a DCC loco with a speed curve enabled. I'd be interested to see the current draw comparison. Perhaps the lights etc draw a large baseload current?

many thanks for replies, looks like its a quirk of the new design, as said very pleased with my 40159 and looking forward to the sound version shortly.

trying to resist the urge to buy another. (somehow I think this may fail).

as per Longbow's observation, throttle response seems a tad sluggish at the bottom end, certainly up to about 60% on my controller, the lights at both ends are certainly bright, particularly the red markers. Above 90% the speed doesn't seem to increase any. I usually run on DC at no more that 80% on the newer Farish stuff.
