That's some pointwork , awesome stuff

Sorry if this has been asked already but can't remember reading it, but how many people are working on this project?  If it's just a solo effort then I think it's coming along really quickly and really well.

Although there are a number of people from the old "Bradfield" operating team who contribute with research and suggestions, the build is predominantly a one man effort so many thanks for your compliment.

As I said about Bradfield John, I do like a good urban terminus even if model more rural scenes.

Hi John

 

What is the function of Signal 53 on Platform 1 please, seems a bit pointless?

 

Ian

 

 

Given it is a main aspect stop signal, I can only imagine that it is there to split the platform, to allow two trains (of two or three coach lengths?) to rest there when required.

(Edited to remove superfluous "stop" (I thought I'd already got rid of it, blo0dy thing))

 

Sorry, a bit late to this.

 

It's likely to be a mid way repeater to allow staff starting short trains standing at the stops to determine if the main departure signal was off, i.e. to help prevent the ding ding and away SPAD as it's called these days, where the guard whistles, the train leaves and the driver has forgotten the signal which could be at danger - this was the basic cause of the Paisley collision in 1979. I imagine that platform was often used for short trains hence the provision of the signal.

 

Two trains standing in the station don't need departure signals, the staff on the ground would handle that and <I reckon> there will be instructions which state that drivers must wait for the signal to be returned to danger and then cleared again before departing when following a train.

Fair argument - would not a banner repeater have sufficed (if they had been introduced at that point in time)? Given the signal has its own identifying number, the implication is that it has its own lever / control switch - if it was a repeater of some sort, I would have thought it would be automated in some form. Or is it a case of different standards due to time period / pre-nationalisation owning company?

I am just making a bit of a guess here but I wonder if signal 53 is a second starter signal because the one at the platform end may not be visible to the driver of a short train at the buffer stops.

 

So if there are two short trains there, the driver of the rear one may not be able to see that the main starter has returned to danger after the first one departs.

 

So the first train to depart would do so on the main starter signal but the rear train would start when both signals were cleared. At least that way the driver has a clear view of a signal before they set off.

 

I don't think that I have ever seen a repeater with its own lever number but I am not nearly as well informed as some good folk on here and could well be wrong.

Despite yet another bank holiday and all the socialising that it generates, more progress can be reported. My visitors are now being press ganged into service with the P Way dept, "Leander" is responsible for over half the timbering on the latest section of P&C work. This is the final piece of the jig saw for the junction box. Access to the North Carriage Sidings is gained from the North Departure, over the North Arrival and via the slightly curved double slip with swithced K's.

 

 

Tempting as it is to get some of this fixed down and wired up, I intend to crash on with more pointwork!

[the penguin of doom]

This is stunning work and for an ex signalman like me, a great way to, (eventally), spend time watching the trains go by.

 

Can't wait to see the layout out on the circuit.

 

Cheers.

[yorkie_pudd]

simply mind boggling fantastic work and great to watch it all fall in to place John.

Guess what Sean, neither can I. Cheers mate!

Superb track work

Thank goodness the crossing timbers stayed stuck down.

[Bulleidnutter]

As a great news reader once said. B E A UUUUUUUTEEFUL! Lovely work. The eye just begs to follow the curvature.

To add to all thats been said, great project, amazing track work. I was looking at the picture of the double slip with switched K's, it does not seem as though the blades would have enough travel to be able to open far enough on the different roads. Could you explain how the tie bars would operate and where you have soldered, as I really like the formation and would like to use one on my own layout.

[TheLaird]

Having gone around the bend, it will be seen that we are now in Leeds City Wellington box territory heading towards the station. This next piece of P&C work comprises a crossover from platform 4 road to the North Departure and a crossover and double slip that gives access to and from platforms 5&6 to the South Arrival and Departure lines respectively. The slip is a 1:8 with switched "K"s, not prototypical but as all the heavy trains use P5&6 I wanted to be on the safe side (The prototype is built to finer standards!!).

 

 

There is one more turnout to go in the South Departure that leads to the South Carriage Sidings and then next up will be the two scissors crossings that sit either side of the signal box at the end of platforms 3&4. These formations are proving quite challenging to design and I have just realised that I need to tweak them again.

Hi Tom, not sure exactly what info you need so I have taken the following close up that will hopefully help. Regarding tie bars there will be six in all, two at each end for the curved roads and two in the centre for the switched "K"s. the ones at the ends will work together and the centre ones work opposite each other. The copperclad strip is of course a departure from prototype fidelity but I feel a good compromise in ensuring reliablity and strength.

Loving the sweeping track work.

Hi John.

 

I have just discovered your layout thread. I'm going to watch this with very keen interest. This is mainly as I live in Leeds but also I am modelling the Bramley station and the Pudsey loop, which is less then 5 miles from your modelling location. I have done much research on my location and have plenty on Leeds and surrounding areas, so if I can support you with anything just give me a shout.

Hi John,

 

Thanks for your response, from the picture and your description, I think I have a good idea how this formation works, I have a need for a double slip but the location would not allow due to a less than 1:8 crossing angle, your formation would fill that need, so thanks again for sharing.

I have completed the point that leads to the South carriage sidings but not worth uploading a picture. I have now finalised the design of the South Side Scissors crossing, the trick is to get all the crossing noses on the same timber, not as easy as it sounds!!

 

 

The points are all B8s, so I had to widen the spacing between tracks to get the correct alignment. I have also resorted to checking photos of the prototype to make sure my timbering is correct, the difficulty is that it appears to have been relayed sometime in the late fifties with a slight difference in timbering. Here is the beast in question:-

 

 

The later pic on the right shows the difference with the middle wing rails extended to form a continuous check rail along the curve. It also looks like flat bottom rail. As I intend to turn the clock back at some stage I have gone for the earlier design.

John, you're amazing at seeing the differences, I doubt most would see that check rail, would it have been extended because of the peak locomotives ( CLASS 44/45/46 ) entering service ?

Looks like bullhead rail to me - the rails are sitting completely in the chairs and have wooden blocks to stabilise the rail (I can't remember what they are called).
