One of the requirements of the HMRI was that bridges and viaducts should have substantial parapets a minimum of 12" above rail level and capable of restraining a derailed vehicle from falling off said bridge/viaduct. In the absence of such a parapet then guard rails were required, THe only plac...

Currently the public shop only has the original frame code LF5, the Mk 2 frame code LF25 is only available from the members' store.

Make the gradient as flat as possible within the constraints you have, haulage capacity depends very much on the locos and stock you want to use.
I have grades in the region of 1 in 25 and need heavy locos but it does work.

Oddly enough a Google search for "GWR Journal index" takes you here http://www.gwrjournal.com/ as the top entry.

The difference is in the dimensions. However that difference results in different allowable maximum speeds over the diverging track, the speed increasing with increasing radius which relates to the switch designation. A switches are the smallest radius and hence lowest speed, of use only in shunting...

I have managd to re-install JMRI and have set up a simulation for your frame using only ADD conditions as would be the case if using CANCOND firmware. All appears to be OK, so far as I can see the locking works as required. Clare frame for JMRI.zip It uses JMRI 4.12, if the panel does not come up pr...

Monty,
What question are you looking for an answer on?
The original question was answered long ago, even though the question has since been edited out leaving the question to be deduced from the answers.
I can't see any other unanswered questions.

I'm with Noel. Sheets were standardised very early and multiples would be used if needed for a special load. A small stock of non-standard sheets for occasional use would have been far more trouble than they were worth,

This link https://maps.nls.uk/geo/explore/#zoom=19&lat=51.5114&lon=-0.0664&layers=173&b=1 gives you a rather better version of the nls maps to explore. You can scroll through the whole area, zoom in and out and the slide control allows instant comparison with current arial photos. Ch...

I dodged the melting and casting bit. After replacing lead water pipes I just cut them into lengths around 4 inches, bashed them flat with a hammer and have been using them for tracklaying ever since, As seen here.

Only just managed to get back on line following a computer problem that hit when I had almost finished the locking table last night. Wiped out that work as well as the web access. Anyway while off line I did manage to redo the table so here it is. locking table.pdf locking table.ods There are a coup...

Yes

David, You took my words to heart wrt 'locks' but ignored my mention of 'released by' When translating locks R to released by there are one or two omissions. I'll try and work out a table shortly. Rgds PS. With double line signalling where there was often a procession of trains needing no change to ...

Looking at levers 5 & 6,you have 6 released by 5. This implies that the lock lever stands normal when the points are locked, and that the points are only locked in their normal position. This is probably the less common option for lock levers but is perfectly acceptable. However having chosen th...

Yes I m aware of the lower ballast level you cheeky so and so. But I am laying my track on 3mm cork so having cut this away as I think Mike suggests in his article, Im left with a bit of a trench that’s a bit deep I feel. It won't be so deep after you have added ballast at the bottom of the trench,...

I agree Jol, but its not a winnable battle so not worth fighting
Much worse is 00/H0 scale.

Looking at this it seems that the etching provides only the rails, no working parts and no cosmetic parts for the deck.
And even the rails are not all the right length.
ie. You are left to do all the difficult bits yourself

For a bogie, an additional chord needs to be added to the model (chord c. which adjoins chord b.) representing the wheelbase of the bogie. Not really, just do the calculation seperately for each wheelset using 'b' as the distance from wheelset concerned to the driving wheel. And if you want the sid...

self contained, strong , well made and rigid Neither the Bachrus or DCC Concepts are really self contained or rigid, both are designed to sit on a length of track and get their rigidity from that. Other than that either look to be good. no personal experience however, I have a set of the original S...

Probably pay to cut a V notch in the bottom of the remaining boss also, to reduce the stress when inserting axles. The idea is shown here, http://www.clag.org.uk/pics/bearing-interface/vee-slot-pinpoint.gif but for a plasic bearing just do the bottom Vee with a scalpel, easier than with brass bearin...
