This thread is moving on twice as fast as normal - you can tell everyone’s stuck at home! I love the diesel photos Tony - I don’t think I’ve seen all of those locos before.

 

Could I ask you for a little ‘virtual loco doctoring’? I have a DJH A3 (second hand - not built by me although I have sorted it out a bit see https://www.rmweb.co.uk/community/index.php?/topic/135510-coulsdon-works/&do=findComment&comment=3856937

if you’re interested but not relevant to this question).

 

It  is giving me problems with stalling over crossings. It’s fitted with ‘American’ style pick ups which I know aren’t your chosen solution, but I think you agree that they normally work OK. This loco seems to stall at exactly this point on my diamond crossing unless going at a fair lick in which case it still twitches noticeably. If Peco did a code 100 electro frog crossing I’d switch (pun intended!) straight away...but they don’t.

The front driver is on the plastic bit but I can’t see why the others two drivers don’t pick up - they are live. Some other locos struggle here as well so there must be some unevenness in the track but I can’t see where. Pick up is on the left for the loco and right on the tender (Right way up and facing forward). Here is the arrangement from below.

My question is: “Could I improve things by making the bogie and/ or Cartezzi truck pick up as well. And, if so, what is the best way to do this - do I need new wheel sets or can I short out the existing ones?”

 

Thanks in advance for any help.

Strangle enough I have exactly the same problem on my DJH loco but I have conventional pick up on both the tender and loco.  In my case a good cleaning of the point contact blade has all but eliminated the problem.  It is also in a very convenient location at the end of a cab section so I think I can hard wire the point blade and short exit section.  Re your specific problem, based on what I have seen over here the non pick-up wheels were insulated, would it be possible to put pick-ups on them?  Until mentioned I had forgotten about the shorting issue.  It is possible but on mine the short happened in other places like going from a straight section to a curve and when running in reverse.  I found them when I ran the loco with the room lights off.

Excellent.

 

The other non Thunderbird Thunderbirds classic craft that I wouldn't mind a model of is Zero 1. The original was over 7ft long and apparently cost over £3000 even back in the 60s. This is one offered on ebay:

So glad Thunderbirds had a revival when my son was young.   In fact my grandson was introduced to a rather battered Thunderbird 2 only last week. 

Whatever happened to our (non-Blue Peter) Tracy Island, hand built so I'm sure Tony would approve, with ramp and door features operated by motor/gearboxes from old camcorders?  Such fun!

I’m no loco doctor, but I was having similar problems with certain locos on my crossings and it turned out it was the crossing itself, it was jumping on the insulated part and shorting out on the other rail, worth investigating.

A few pages back I mentioned Comet Metal Miniatures of sci-fi cult film/programme vehicles and offered to dig the ones out I had, all assembled and hand painted many years ago, and post up a pic. Well, I've found them, given them a quick dust and here they are. Apologies for the thread drift and not being trains, but I guess it is a bit of modelling:

Re: LNER Locomotive Classifications

Not to mention both Gresley and Thompson O1s

Edward Thompson always seems to get a bad press (perhaps not always fair), but he seems to show an 'arrogance' at times.

 

Take the LNER loco classification system for instance. OK, it might show an arrogance on Gresley's part that, at the Grouping, all the ex-GN types took precedence - A1 (the GN never built a 4-6-0), C1, D1 and so on, followed by the GC, GE, NE (second with its Pacifics) and so on. When new locos were built under Gresley's regime, they merely took the next number in the sequence (the A3s and the A4s were obvious predictions in 1923); thus B17, D49, J38 and so on.........

 

Along comes Thompson, and he'd have none of that. Not at all - all his locos would take the lowest classification - Gresley's A1s were booted down to A10, the lovely-looking GC B1s and B2s lost out to Thompson's 4-6-0s and so on and so on.......

 

He must have been miffed when Peppercorn 'demoted' his A1 and A2s to mere sub-divisions.

 

Regards,

 

Tony.

The topic of pick-ups came up recently......

 

Obviously, good pick-up is essential for good running. However, by employing dead-frog points/crossings, then good running is compromised. If such non-conductive track configurations are used, then the maximum number of pick-ups is required.

 

2104150830_pick-ups03.jpg.b938e1adfc3ad45f3f3900e54c38182d.jpg

 

I built a London Road Models D2 for Mark Allatt for use on Grantham. Since Grantham has several dead frog configurations, to prevent stalling I installed tender pick-ups as well. The non-insulated side had the pick-ups fixed directly to the frames. Shorting out the wheels on that side would also have worked. 

 

A better solution all round would be to only use live frogs. 

 

Since all of LB uses live frogs, I have no need of tender pick-ups. I thus configure them in the simplest way. Since I don't use DCC, the majority of my locos are live-to-one-side. 

 

1330142768_KingV207.jpg.de124ea2cbefdc2f7d7378ebb2bfc079.jpg

 

Like this - for a Graeme King V2 on top of a Comet chassis. Small-bore PVC tubing (Mercontrol) obviates stray shorts. 

 

118930889_pick-ups01.jpg.82e394051f1918bc7642a2f6cfa5a059.jpg

 

And, the same on an A2/2. Note the tapped hole in the front spacer - to take a shouldered screw. 

 

85226512_pick-ups02.jpg.56f8f2f4917e17c01b440407efbdd828.jpg

 

The wheelset I had for the DJH 'Semi' (featured in this month's Railway Modeller) was all-insulated, so two sets of wiper pick-ups were required (better for DCC as well). No sleeve-insulation was necessary. 

 

1394057465_pick-ups04.jpg.df96a7a67395a4c5e26634dd2884d0bd.jpg

 

Even if a live chassis is employed, sleeve-insulation is not obligatory; as long as there's plenty of clearance. Note the forward extension to give access for a crocodile clip for routine testing. Also note the use of shouldered screws (or one with a collar) to hold the bogie and pony in place. These are easily tightened-up - much better than using a nut. All the bogie/pony/tender wheels are live, meaning return is via ten points of contact.

 

The pick-up wire is .45mm nickel silver wire. I've had occasion to investigate poor running on locos using phosphor bronze as pick-up material. I just scrap it and replace it with nickel silver. 

 

I hope some of this is useful.......

I have no wish to be disparaging about more-recent naming policies on our railways, but to have fine locomotives named after PUPPETS seems to me to be scraping the bottom of the barrel! 

 

I know these are 'rescue' locos, and one can see the connection, but when one thinks of the names these previously-Class 47s used to carry - GREAT WESTERN, SIR DANIEL GOOCH, ISAMBARD KINGDOM BRUNEL, etc., then what a comedown. Even some of the later ones - RAF KINLOSS, THE SAPPER, ST. CHRISTOPHER'S RAILWAY HOME, DIAMOND JUBILEE, THE INSTITUTE OF CIVIL ENGINEERS and what have you have a dignity.

Goodness me Tony, this was from the 1990s when Virgin was marketing itself to the hilt on the West Coast upgrades.

 

It was a clever piece of marketing right out of the books of the LNER who were not averse to generating publicity - why else is the Flying Scotsman so famous.

JohnSmith of GBRf has given his locos some interesting names and liveries.  He’s also used them to recognise long serving members of staff and customers.  He, too, is not adverse to some publicity and has built a remarkable business since the late 1990s in the freight sector.

Yes they were primarily rescue locomotives and also used to haul electric trains (Pendolinos) over non electrified lines, Settle & Carlisle, Holyhead etc so in my mind cleverly & aptly named for the period.

 

The western region Brush 4's indeed had superb names. Here is "George" at Sheffield Midland 3 January 1970. My favourite was Odin, first named Brush 4 I ever saw southbound at Wigan NW late 60's

I think you underestimate just how loved and revered the work of Gerry Anderson was, Tony.  There are generations of children around the globe who grew up watching those TV episodes on television, and were/are/will always be passionate about them.  To you they may just be puppets, but to many of us (myself included) the work of Gerry Anderson in the 1960's/1970's is iconic.

 

Yes, it is a shame that the old names were retired as a result, but it's great to see more late 20th Century icons and institutions being chosen to name locomotives (and aircraft of some airlines fleets, for that matter).  And in the case of these in particular, given their roles, a nod to the TV Show Thunderbirds is about as appropriate a set of names as you're ever likely to see.

Thanks to all who offered advice on my A3 pick ups. I have made progress this morning, by shorting out the two bogie wheels. This was much harder than expected as the metal block which holds the bogie wheels was painted in a non conductive paint and the bolts attaching it to the main chassis were also insulated. So I had to ream out the axle holes slightly to remove the paint and then solder a wire between the bogie frame and the main chassis. This was made harder by the issue which Tony raised as the nuts securing the bogie in place had been glued on and I couldn’t free them up so had top work with the bogie in situ.

 

Anyway, thus improved it works much better. The loco glides over the crossing perfectly, however, the tender still gives a slight twitch (but doesn’t stop) when it crosses with the other side pick ups. I could solve this with a pick up on the insulated side of the loco.

 

However, I thought four wheels picking up (on the tender) should be enough for anyone. So this led me to investigate the crossing further and I found that there is an almost imperceptible rise over the centre of the diamond crossing. This means that the plastic frog is the highest point and just as one wheel is on the plastic the others have a tendency to lift of the track - hence the stall. This is exacerbated by the plastic frog crossing section being much longer on a diamond crossing than on Peco insulting slips. I don’t understand why this is necessary.

 

Anyway the solution looks to be to lift the crossing and try to remove the ‘hump’ in the middle. That won’t be easy and will have to wait until I’ve finished running my sequence through on the Gresley Jn thread. 

 

As I’ve said before, if only Peco did electrofrog diamond crossings in code 100. I know I could switch to code 75, but I’ve too much invested in code 100 for the time being ..... and if I can’t lay level track in code 100 what chance in code 75!

 

I hope this experience is useful for someone and I haven’t bored the rest of you too much. Thanks again for the help.

 

Andy
