Springfield Junction - Present day 00

This is a permanent layout built in a shed. Spike Taylor is the owner of the shed and I'll be helping him put it together. (Spike is the main scenic man behind Blackmill and the rebuilt New Bryford)

Built on two levels with storage roads along both sides on the lower level and one side on the upper level, the emphasis will be on running trains. Some of the roads will be long enough to hold 20 wagon HTA or HHA rakes. The main circuit will be double track with a junction based upon part of the layout at Hellifield station - but there won't be any platforms.

 

The main lower deck has been constructed with 18mm ply tops - along one wall they're on kitchen units and the other has an open frame/stud construction, making space to store stock boxes under the layout

We've kicked around the basic design for a couple of weeks and the two levels will be connected by bi-directional ramps. This view effectively shows how the width will be used. We're trying to keep the gradients as long as possible and the curves as wide as possible. Left to right, two lines will be descending from the far end to near, next track will be coming up towards the camera. the next six are one of the lower level yards - all of which will be bi-directional

As it's a permanent layout, we haven't designed in a liftout/lifting section, putting up with the bending underneath, so it means less track joints and wiring across the doorway.

All trackwork will be Peco Code 75, pointwork will be controlled by Peco motors using a capacitor discharge and diode matrix.

 

BTW, the shed is 25' x 8's so we've got about 24'6" x 7'6" to play with............

 

Cheers,

Mick

Sorry no photos as we packed up all our templates before realising that we hadn't recorded our work - although it is all documented in a note pad.

 

Did some more work tonight in the planning department.

To create two LARGE storage areas on the lower deck is going to take 31 points, with associated motors and switches, about 5 boxes of flexitrack and an equally large number of railjoiners and track pins. Not a small outlay for that lot!

 

We've also worked out that the two main access ramps between the lower storage and upper main loop will be 1in49 and 1in40 gradients.

 

Next stage is to cut some triangular formers (basically a long thin wedge) for the gradients so that we can simply place it on the trackbed and put a spirit level on top to make sure we're building the ramps at the correct incline.

Also in the pipeline will be large amounts of plywood, cut to large radii - about 40-44", that will form the trackbeds on the curved ends.

 

Next update will probably be a couple of weeks due to work commitments.

 

Cheers,

Mick

Great start Mick. Looks as professional as one would expect with your crew.

This is Spike's baby really - he's the man with OCD when it comes to things being straight and level!

 

Cheers,

The pointwork has been ordered and an advance shipment procured so that we can confirm our original template work.

To make it easy to identify the various storage yards and pointwork, the notation of north/east/south/west has been used, based upon the actual orientation of the shed.

 

This is the north east corner

post-408-0-11750100-1380148626_thumb.jpg

 

The north yard will be 10 roads - effectively 9, as one road one will normally be used as the continuous lower loop.

South yard is 6 roads.

 

The wood should be cut this weekend for the curves and inclines to be put into place. As previously mentioned, the gradients and curves will be eased as much as possible. The track from the point by the wall is the ramp to the upper scenic deck and will hug the outside walls at about 44" radius on a 1 in 49 incline.

 

The point motors will be surface mounted wherever possible, as will most of the wiring. Simply for ease of access. It will be routed via slotted cable trunking to keep it all tidy.

 

The blue line is the upper deck - laser levelled!

 

Cheers,

Mick

The gradients are going in.

 

This is the East curve - rising from the north yard towards the upper deck - 44" radius and about 1 in 49. In front of this will be the low level connection between the north and south yard

A quick check with some temporary lengths of track to confirm clearances.

The track bed on the left is the other gradient climbing up the other way - this will be connected to the trackbed in pic 4. (Don't worry, it won't be that steep!)

Once it's around the curve, it splits into two. This actually allows us bring full length train up from the lower yards to the stop signal at the junction (on the upper scenic deck) and still allow a train to descend back into the lower yards.

 

This is the west end of the shed. The upper section is the end of the double tracked climb from pic 3, the curved section on base level is only loose in place and will be made to rise up to the top deck. Coming out in pic 3 above.

We haven't yet done any full length train testing on the gradients to see what can be hauled up. That may happen tomorrow night with some temporary track and stock.

 

If we have a serious issue, we can still reduce the height of the top deck to ease the gradients. At present, the planned height difference is 200mm, but we could take it down to 125mm, but that would reduce the manual access to the lower yards.

 

Cheers,

Mick

Gradient/haulage tests were carried out a couple of days ago. Using HHA and HTA's as these should be the largest/longest/heaviest trains that should be running.

 

Things weren't looking too good when the loaded HHA set wouldn't roll DOWN the slope. A Bachy 66 managed 12, whilst a Hornby 60 could just struggle with 15.

 

Next up was a very free running HTA set of 19 - a 66 had to be "driven" to prevent excess wheel slip. We couldn't try a 60 because we haven't got a buffer (tension lock) fitted HTA yet, but if the 66 could cope, then I'm sure a 60 will.

 

A quick inspection of the HHA's revealed a bit of gunge within the pinpoints. I've had this before with Bachy HEA's in the past that became very reluctant to roll. It was explained to me thus by a Bachmann rep over 10 years ago. It's because the chassis is made from a ABS based plastic that accepts paint easily, but it isn't "self-lubricating", such as nylon or styrene based plastics. Eventually, it wears slightly within the pinpoint area creating a powdery residue.

Once this had been explained, I cleaned out the HEA axle ends and it transformed the free rolling ability.

 

A quick clean of the axles on one HHA  and it started to roll down the hill, so problem identified. Plan is to clean out the HHA set and use a small amount of dry graphite based lubricant. If this doesn't work sufficiently, then we'll look at fitting brass bearings.

 

This is the first test run of the HTA's

This shows the gradient compared to level (plywood edge)

I have some video on my phone that needs to be transferred to youtube first. I'll post that as soon as poss.

 

Cheers,

Mick
