Re: Track on bridges and viaducts

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...

Re: track inclines from level to standard bridge height

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.

Re: Types of points

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...

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.

Re: Goings on at the Norfolk Wagonarium

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,

Re: Brimsdown-The last grand project.

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.

Re: Signal box diagram - views please

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,...

Re: PH Designs Wagon Turntable

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...
