Initial euphoria was tempered with a modicum of disappointment as they are actually a bit poorly and will need repairs before they start 'ting!'-ing. Nevertheless, thanks to Barry Young for bringing these to my attention. Room for more if there's any others gathering dust out there ... It was a shame that they were only available for a short while and are quite rare nowadays. What a nice find! I can't help but think that a similar product now would sell well as my perception is that there are many more modellers around wanting to use such things to make their operation more interesting and realistic. I think they were a product well ahead of their time. The technology on those is relatively simple and wouldn't be too difficult to recreate with some laser cut boxes, coils scrounged from old solenoid point motors and a few bits and bobs such as a rotary switch and a needle that is attracted by a magnet plus a bicycle bell.

Trouble is, it's instantly adding complexity and not very 'traditional' ... Happy to oblige. Nothing so grand as a commercial solenoid for the bells, just a home wound coil of enamelled copper wire. The Meccano arm allows the bell to be adjusted to give the best clear ring. The instruments themselves use lights rather than a needle. A wiring diagram was published in MRJ issue No 60 way back when. They are basically a rotary switch with the lights at both ends wired in series. The tapper for the bell is a simple sprung plunger on the block instrument. If you need any more detail please let me know and I will be happy to help.

RMweb Gold 5BarVT Posted May 30, 2021 RMweb Gold Share Posted May 30, 2021 With an external clapper or adjustment on the bell position (as t-b-g above), the loudness can usually be varied. More difficult when it is just an internal solenoid. The trick is to have the solenoid/coil reach the end stop just before the clapper strikes the bell, “how much” before determines the loudness. If you want needles rather than lights, just use a centre zero ammeter at each end, also in series (and suitable series feed resistor). + for LC, - for TOL, it’s how the big railway did it. I’m being deliberately vague on which ‘big railway’ as GW was one polarity and Southern was the opposite and I can’t remember who was which!

RMweb Premium 31A Posted May 30, 2021 RMweb Premium Share Posted May 30, 2021 Re Block Instruments, here's some I made earlier; probably about 30 years ago for a layout I built with my father in my parents' loft. The solenoids are probably some sort of Government Surplus, most likely from a shop in the Tottenham Court Road! They were worked from three-position GPO key switches on the panel, which also transferred traction power from one controller to another and also unlocked ( = made the point motor feed live) the points at the junction, so they had to be used in order to run the railway. At first we just had white, green and red lamps on the panel to indicate Line Blocked, Line Clear and Train on Line, but I thought we ought to have some proper instruments so I made these; they hung above the control panels. We used a doorbell as a Block Bell; we only had one as we know which one of us had dinged it! I modified it somehow by bypassing the 'interrupter' so that it worked as a single stroke bell, but the bit of wire seems to have fallen off now and I can't remember how I did it. 8 1 3 Link to post Share on other sites More sharing options...

Those look really lovely. There is something charming about a home made item like those block instruments that seems to have been lost in the modern world of telling a machine to cut what you want with exact precision. With the greater accuracy comes a loss of character and individuality. 2 2 Link to post Share on other sites More sharing options...

About 50 years ago (crikey!) the late Ray Hammond taught me how to do that. Use an ordinary external-clapper bell and run it on DC. Bypass the make-and-break switch and adjust the clapper so that when the coil pulls it in it is just short of the bell. When you energise the coil, the mass of the clapper makes it continue just far enough to contact the dome and sound the bell but its subsequent vibration doesn't bring it close enough. That way you get a clear ding not a thunk. 4 Link to post Share on other sites More sharing options...

They were operated by rods with handles on from inside the saloon and told the driver a passenger wanted to get off. The thunk was annoying until we realised that we had to allow the clapper to bounce. It worked well after that. This was learned the day before we started carrying passengers with a deadline looming.

Popular Post LNER4479 Posted May 31, 2021 Author Popular Post Share Posted May 31, 2021 (edited) Anyhow ... Even though the layout is part dismantled for a few months, that doesn't stop work on other things. Ladies and gentlemen, I give you 2021's loco build project: Only been 'in stock' for about 20 years(!). Wish me luck ... In fact, nothing like a bank holiday weekend to make a start. Chassis is a bit basic(!) so I'm already adding things. Spring hangers (from a spare B3 etch!), holes for brake hangers, motor cut out filled in, slots for motion bracket supports and bottom rear of frames profiled more accurately. No Poppy's jig required - it all bolts together in the traditional style. Although not apparent, the bearings for the centre drivers set just slightly high, to avoid grounding on any high spots. Drivers are an old set of Romfords 26mms I had to hand - this will be a 'layout loco'! Footplate assembled from four pieces. A fair bit of fettling to get them to behave. Doesn't quite look like a Pat just yet but give it time. The important thing at this stage is ride height and driving wheel clearance (being 26mm helps). Haven't got a motor/gearbox for it yet but I'm planning on this being a 'heavy hauler' due all the weight it's carrying around. Might even get called up for overnight sleeping car train duty over Shap. I also fancy it in early BR appearance, possibly in lined black which some of them went into before getting their better known cowpat green livery. More as and when I get round to it. I fancy this might be a gradual job throughout the rest of 2021 - there's other things on the agenda as well!

LNER4479 Posted June 2, 2021 Author Share Posted June 2, 2021 I enjoy looking at books and sites like Rail-online to try and select a suitable loco, obviously looking for one that would have been seen regularly at Carlisle, typically either shedded there or somewhere like Crewe. 45524 'Blackpool' is cropping up quite a bit. There's also the riveted versus flush tender nettle to grasp (the kit comes with the latter). The devil in me rather fancies it in lined black with 'British Railways' on the tender; anyone happen to know when the last one ran like that? 1 Link to post Share on other sites More sharing options...
