Halton Boy said, The ground frame would only control the platform line point and its trap that you have labelled 1a and 1b. The other points in the up sidings would be hand points with levers adjacent to each point. The ground frame is only there to provide for 1a and 1b to be interlocked with the signal box. Lever 1 in the signalbox, when pulled energises an electric lock on lever 1 in the ground frame allowing that lever to be pulled. While the ground frame lever 1 is reverse the signalbox lever 1 will be locked, by another electric lock, in the reverse position and that will prevent the home or starter signals being cleared. The ground frame lever 1 reverse will release ground frame lever 2 which will actually operate the point and trap. Yes.

I agree with Jeremy. 9a and 9b are traps, nothing to do with a single slip. Its possible if they are double tongued traps that they could look like the blades of a double slip, but more commonly they would be single tongued traps. A similar installation can be seen in photos of the pre-preservation Bodmin General among other places.

You are both right here, nowadays H means yellow and D means green but the origin of the H and D is Home and Distant. Both current practice and historical origins are correct, depending on context.

Given that the BS 376 costs a ludicrous amount and BSI are very protective of their copyright you may find this helpful. https://dickthesignals.co.uk/onewebmedia/4 introduction to plan symbols.pdf

I have added my answers to your text, hence you need to 'expand' to see them.

Good to hear my suggestion being followed. Despite those on here saying iwould be to difficult.

I have always used PVA and glue the track and ballast together in one hit. Nowadays I use PVA from suppliers catering to childrens activities designed to wash out of clothes. It can be soaked and the track lifted if neccessary but it certainly doesn't loosen at the first whiff of wet, there would be no problem if ballasting in a second hit.

Its all Network Rail, if they can't manage these things then they are not fit for purpose, all S&T would need to do is bond for the track circuits, or maybe move an axle counter head, it would just use the existing down fast signalling with a TSR.

A decent P-way and S&T team could slew the down fast into the upfast either side overnight then you would have one up and one downavailable with no need for pilot working or handsgnalling.

That quote is clearly referring to using the DC controller to control the speed without the bluetooth, not to setting the controller on full whack and using the bluetooth. Part of the problem of inadequate answers to poorly expressed questions. Better just to be patient and wait and see. (And a good PWM controller would not be doing any pulsing at full chat so should be just fine. Its a poor design that still pulses as that means it never gets to full voltage).

The competion seems to be more in the other dirction, who can charge the most.

Meanwhile another release of the TEA with no change to the dreadful old Triang bogies that completely spoil it.

Would be nice if they included some pictures that revealed what they actually look like. The views given don't show anything looking like a vacuum pipe.

The new r 2023 section on the Hornby website seems to have the photos for these and the bogie bolsters mixed up.

The lift plates mentioned are the fishplates, joggled in the centre so one end is higher than the other.

But doesn't really answer my question. How do you know that only 4 have been sent back?

I would think the 4 needs to be calculated as a % of those you know about, do you really know 1600 purchasers? Or are you getting this info from Hornby?

When we were discussing this with the RI for DLR the main issue was the ability of passengers that may have to be evacuated from a train to get up from trackside onto the platform. As such locked gates were not acceptable. The gates are just sprung and fitted with warning signs. The older stations had narrow ramps but these can be hazardous in wet or icy conditions, steps are better.

Best IMHO to buy cased ones, the small ones usually come with a two wire figure 8 connector or as wall warts with a plastic earth pin and the bigger ones with a 3 pin connector, trefoil or IEC. ie. https://cpc.farnell.com/pro-elec/pel00398/ac-dc-power-supply-12v-1a-2-1mm/dp/PW04113?st=12v ac power supplies https://cpc.farnell.com/xp-power/vet24us120c2-ja/adaptor-ac-dc-12v-2a/dp/PW04584?fi=wp https://cpc.farnell.com/pro-elec/pell0304/ac-dc-psu-12v-5a-2-1mm-ra-dc-plug/dp/PW04958?st=12v power supplies

That depends, if the output is fully isolated from the input then you can. This usually only applies to units of 60W or less with a 2 pin power cord. Where they have a 3 pin power cord then the 0V of the output is usually earthed and joining a Pos and Neg will short one out. But for tortoises you should be able to use units well under 60W.

I was going to suggest you looked for a tour on this, https://schwebebahn.de/en/kaiserwagen which I did a few years ago but there is no date yet for resumption of service. Was nice though, gliding through the stations with champagne in hand.

Any point can be made into insulated frog just by creating 4 gaps in the rails round the frog. Rule 1 applies, if you want to do it just do it. has no relevance to live v insulated what is the advantage if you don't connect power to it? What the SM said above.

Juicers might be easiest but they are a lot more expensive than using the switching already built in to the decoder and/or point motor which Kallaroonian already has available.

I would always use a hard control panel or JMRI so can't really help with your ECoS. It does illustrate the problem of relying on commercial products designed for control of toy train pointwork and not allowing for models of real railways. A standard crossover needing two sets of frog switches should be a normal provision in any design. But I would expect the ECoS to allow the two outputs of the decoder to be switched with one command, rather than trying to put two motors on one output. If the ECoS has route setting then you just need 3 routes, all straight (normal), 1&2 reverse with 3 & 4 normal, and all reverse. It helps when drawing the plans to show point in the normal position and where they form crossovers and work together label them as A and B. Here I've tried to show the frog switching as well.
