2mmFS Thoughts on a Layout


Ian Smith

1,021 views

Over recent days, I have been thinking about the type of layout that I eventually want to build. As I already have the beginings of a GWR BLT in P4, I wanted something a little different but still a GWR branch line theme (I have a fondness of tank and small tender engines), I also want something that could be built in a reasonably short space of time, and hopefully even exhibit. However, I did not want another BLT, so my thoughts have wandered towards a through station of some sort - I even considered a length of plain track with perhaps a viaduct or something as a focal point (but I really do want something that could hold a viewers attention for more than a couple of minutes).

 

For many years I have harboured thoughts of building Gara Bridge station on the Kingsbridge branch, but a look at the plan indicates that I would need quite a lengthy space (even in 2mmFS) - and I really wanted to keep the scenic section to less than 5 feet long by no more than 15" deep. A look at the other through stations on the line (Loddiswell and Avonwick) have a very simple track plan (and anyway Avonwick has already been modelled in 2mmFS).

 

Although I think that modelling an actual location would be very rewarding, I still personally prefer an imaginary location so that I would not be limited to specific stock prototypes and traffic.

 

To this end, I have downloaded a beta copy of Templot (thankyou Martin Wynne!!), and spent a couple of evenings trying to understand how to draw a plan with it :O

 

The results can be seen in the photos below, I have even placed the stock I have on the plan to get an idea of the lengths for the sidings etc. The idea is that the single platform will be met immediately after exitting the overbridge, a couple of sidings will run behind the platform in a small goods yard, and a loop will allow a small amount of shunting to take place. I am thinking that towards the non-platform end of the loop will be an overbridge so that the line can exit the visible section on an embankment (hopefully strategically placed trees will disguise the exit).

 

The turnouts on the main line are 12'0" GWR switches with 1:7 crossings, the Y turnout is a 1:6 as is the turnout to the long back road.

I think I still need to juggle the plan a little - the 6'0" between the main line and the loop is actually 10'0" (so may be a little too big a gap - thoughts??), and the siding behind the platform needs to be moved closer to the platform. Once I am happy with the plan I intend to mock up some buildings to get a real impression of what a finished layout might look like.

This looks to be a very nice project Ian.

 

You can't beat laying out some stock on a track plan to give a good feel for something...and I do like the simplicity of it.

 

I will leave someone else to comment upon the gap between the lines as that's not my strongpoint...but in my eyes looks fine - don't forget to add the layout to the 2mmFS layout index started by Kris...

I think you could justify 10 feet by assuming the railway was built to 7 foot gauge, before being reduced to narrow gauge :)

It might have been 10', like David says. Don't worry - mine are closer because of the location (and I may have compressed the plan widthways accidentally, and without realising until I completed all the track laying!

 

For me I would put the station platform on the other side of the line and view it through the goods yard unless you particularly want an end loading dock?

Thanks Guys.

 

The reason for putting the platform on the same side of the running line is two fold, firstly I think that access to the platform is normally in the same location as the goods yard in small stations, and secondly, the viewing side will be from the non-platform side - that way you won't notice that the little people don't actually get on or off the coaches :-)

 

I think in reality that the greater gap between the running line and the loop is probably justified, as the 6' is almost certainly the minimum between adjacent running lines (i.e. double track lines).

 

Having looked at the plan with stock on it, I think putting a bend throughout the section where the loop is might be quite attractive too (as originally drawn it is straight from one end to t'other.)

I'm not really convinced by David's suggestion. That might apply on a double track line between platforms, but I don't see it here.

 

The very few GWR branch line stations with loops that I've studied closely have had a gap of about 6'6" between the running line and the loop. This surprised me as I'd expected a larger gap so that there was room for a shunter to get at brakes on wagons in the loop whilst something stood or moved on the running line. In practice, I suspect they were required to wait until the running line was clear before doing anything.

 

That said, all these were loops alongside the platform unlike your plan and I'm sure if you look hard enough you'll find a prototype to justify the wider gap.

It's aesthetically pleasing to my eye. What I'm looking forward to is how you're going to build the track and pointwork. What method will you use - Easitrac or soldered PCB?

I was looking at this and just wondered what it would look like if the entire running line and loop were on a curve. I don't think it would take up too much more space, and it would be more visually interesting from a viewing and photography point of view.

Curvaceous curves for me every time! With regard to track spacing, I thought the same as Dave (Gingerbread) as I read your comments. Certainly Abingdon (the basis for 'Ambridge')enjoyed wider spacing - to quote from the book, 'the track layout at Abingdon was unusual in that there were more sidings between the loop & the goods shed than one might usually expect. This resulted from the Broad Gauge conversion which allowed an additional siding to be squeezed into this space'. ('The Abingdon Branch' N Trippet & N De Courtais, Wild Swan).

 

So there's your excuse - just didn't need any extra sidings! Remember though that the civil engineering (bridges) will also have to reflect the wider gauge.

 

Just my six penn'orth

That seems to settle it - I'll try to bend the plan :-)

 

NthDegree,

The turnouts will all be soldered construction, I have a 3 way and another couple of turnouts that I made donkeys years ago in 2mmFS (that won't be used on this layout) - it really wasn't difficult (although my eye-sight has degraded over the last 15-20 years since they were made :-) ). I would probably use soldered construction for the plain trackwork too - however having said all that I might bite the bullet and model it all in Brunel's Baulk Road (although I would have to see if I can work out how to model it effectively with some test pieces first though).

 

The whole idea for this layout is to keep the plan simple, but still offer a little operating interest, and exploit the space possibilities of 2mmFS so that the whole plan doesn't look like a quart has been squeezed into a pint pot. (For you youngsters those are both liquid measurements from the good old days :-) )

...having said all that I might bite the bullet and model it all in Brunel's Baulk Road...

How about a combination of old and new track, with the sidings remaining in narrowed baulk road and conventional bullhead for the running line and loop? You might even have double-headed rail and inside keys on the sleepered track, though I'm not sure the difference would be visible in 2mm.

Nick,

 

I think that in 2mm people tend to use blobs of solder to represent the chairs in soldered construction :-)

 

I think that the option of having a siding or two in baulk road would be visually interesting, I think I could fabricate plain trackwork in baulk road reasonably easily - it's the turnouts that I think will be the challenge :-) - but if I could I think that the different style of trackwork would definitely make it less of a run of the mill GWR branch line.

 

I think a few more hours playing with Templot to introduce some curviture are needed, and then a few hours with my soldering iron to see what I can achieve in the way of baulk road track!
