I have two and they both run quite slowly and smoothly at fairly low speed on D.C..
The terriers are quite heavy for a small loco which means they have pretty good pulling power.
Using PWM is not usually advised for N gauge motors.

I had one a couple of years ago. Unfortunately, it would stall at low-medium speeds on my Peco large radius electrofrog points going round the curved part. Since this was my main line, such stalling was unacceptable so I sold it on.

A pity, because it is a gorgeous looking little locomotive.

I've often thought of acquiring one because of it's looks. As Webbo says, it's a lovely little locomotive.

I'd also have to agree with austinbob that PWM is not a good idea.

I have four Terriers because they are my favourite loco. Two of them are ok over points the other two stutter a bit, I suspect it's the wheel pick ups.

They are quite difficult to work on because of their small size, the body attaches to the chassis with plastic clips which can easily be broken. For that reason I haven't tried to adjust the pick ups.

If you can find a shop that has a decent test track with points you can test before buying.

I agree with the others about the importance of the correct controller for newer  N gauge motors.

I have quite a few Terriers, which I run on my Langston Bridge layout. I use the Bachmann/Farish DC controller that comes with their train sets, but is often sold quite cheaply on eBay by various people. I find this a most excellent controller, and it operates my Terriers right down to a crawl. The key to good Terrier running is very clean track and clean wheels. I've found I have to clean the track much less often after I applied a very sparing coat of Electrolube contact cleaner. Once in a while you get a poorly constructed Terrier, and there is nothing to be done other than to send it back for replacement.

I agree about the controller, I also use the basic Bachmann controller and have found it very good indeed. They are easy to find on eBay as people quite often split them from train sets.

I didn't realise the importance of controllers until a few years ago, I had an old Arnold controller which seemed fine for my older Farish locos but newer purchases were running jerkily, the change the Bachmann controller made was remarkable.

Hi

I improved the running and pulling power of my Terrier by the addition of some lead in a hole on underside of chassis and the addition of a small slice of lead in the cab and two metal crew members. I use a Vortrak DC controller and with the described set-up the Terrier can run over setrack and other points at slow speed while pulling 11 wagons.

Cheers

Mac

I have 2 terriers bought solely as the will run on my very tight curves, subject to not connecting certain long wheelbase vehicles to the bunker end.

The 1st ran perfectly straight out of the box and continues to do so subject to occasional cleaning and oiling. The second performs well buts has virtually no pickup from the rear axle causing stalling at times. Not unusual for modern locos to have pick-ups not working unfortunately.

Maximum haulage capacity around a Kato oval with 183mm curves is 2 Dapol Maunsell coaches and 5 wagons. Adequate for my needs.

I, like Sillymoo, have 4 terriers. I love them and mine pull quite a bit more than two coaches. I will say that they need to be properly run in and oiled, as I tried doing a short run in and split a gear on the first real load with my newest one. -Philip

I've got one with wheels that go out of quarter on occasions, they can be carefully readjusted by hand.

I am amazed that Dapol have managed to make such a small loco. Another really 'cute' loco is the Minitrix Glaskasten.

How do the Terriers handle Peco ST-5 and ST-6 turnouts? I have very few running issues on my railway but those points sure do cause a few stalls for locos with short wheelbases. A terrier would be a nice addition to my Southern fleet :) I recently bought a M7 and am still tinkering to reduce the springiness of the pony truck, I am simply amazed by how good these Terriers sound at running!

I've got one that has dodgy quartering. How do you readjust it?

The wheels move on their axles so if you are careful you can twist them into the right position. It is a fault on the Terrier model, later models have square ends on the axles that slot into a square opening at the centre of the wheel. This ensures they don't go out of alignment.

Some people have permanently attached the axles to the wheels with superglue but I didn't want to risk doing that. It could end in tears  :'(

You need to be careful when cleaning their wheels and must not push a stalled loco along the track.

Thanks for that. I screwed up the quartering on mine while clearing the wheels.  :-[
Did you get the right quartering by trial and error or did you have some way of setting it accurately. E.g a jig. :beers:

I've got several and they are lovely little models, but don't bother running them on Peco insulfrog pointwork because the wheelbase isn't much bigger than the giant plastic blob. Fine on anything else.

No trouble with slow running given a good controller or DCC. The motors are tiny though so I'd be cautious about using any kind of pulse or feedback controller not intended for tiny motors.

I've also abused them quite successfully. They make a good chassis for lots of little 0-6-0's, and they fit inside even tiny tenders.

I touched the loco briefly onto the track with the power on until I got all the wheels on one side to 12 o'clock and then adjusted the wheels on the other side to 3 o'clock. In my case there was only one wheel on one side out of alignment, if there are more and on both sides it will be quite tricky.

If the wheels are very loose on the axles you might have to resort to super glue or loctite to hold them in the correct position.

If all else fails you might have to send it to Dr. Al.

Good luck.

Thanks so  much. I'll give that a try.  :) :beers:

If you have a brand new loco on the way and find that it is unsatisfactory send it straight back for replacement. Dapol locos have a two year guarantee.

I live overseas in a country with a dreadful postal service so I have to take pot luck.

The advice about careful wheel cleaning and general handling still applies though.

I've done a recount and I actually have five Terriers, so I only had one dodgy one and had I been in the UK it would have been returned.

As EtchedPixels said bang on... One of mine runs like a demented Kangaroo but, with the help of Silly Moo's advice, I'm gonna have a crack at fixing the quartering.

I use a Kato Unitrack starter set (Kato V5 20-864 Variation Oval Set) to test my locos, before they go on my main layout. The advantage is that it is a fairly robust track system that can stand being set up and torn down multiple times. As it also has its own base, it gives a much firmer track for use on the bench, with much less risk of twists, lumps and bumps etc. The last thing you want when testing a new loco is not to know for certain if the fault lies with the loco or the track. Costs around £27.
