Stove R from Hornby Magazine and Dapol

by John Kendall

This model has received some sharp criticism since its release. As far as I can tell from consulting some LMS coach literature the upperworks are correct. It is in the underframe where trouble starts. The running gear seems to be nothing but compromise. I have read that the coach won't stay on the track, particularly through points. Wheels are undersize (at 12mm dia, should be 14mm) and flanges are grossly deep. Brake shoes are miles away from the wheels. It isn't easy to replace the wheels since the wheel mounts are fairly thick plastic and you would have to grind through the bridge from pivot to W iron quite drastically to give 14mm wheels clearance.

I chose to scrap the wheel mounts and replace them with components from Comet Models. I got the C7 W Iron pack (enough for 3 sets) and C14 Clasp Brakes. I reused the plastic axleboxes but in hindsight I wish I had used the Comet cast ones (C17).

Fitting these wasn't easy but after several tries I managed to get all wheelsets at the same height.

There is a LOT of fragile detail, much of it came to grief as I was working on the coach but I was able to repair using lashings of superglue.

I have run the coach on Allingham and it seems to be OK although I must admit I haven't subjected it to any serious shunting.

This picture shows the coach after weathering:



Revision 1 Sept 2011

I took the opportunity the other night (while my power was off due to Irene) to visit my friend. I built his layout and he too has the Dapol Stove R. I wanted to see if my all singing and all dancing Stove R would negotiate small (A5ish) finescale pointwork (PECO and handbuilt)so this was an ideal opportunity. I'm happy to report that it passed with flying colours. The same couldn't be said for my friends example however. Despite fitting it with finescale (3 hole disc) 12mm wheels it appeared to rock on the center axle and was not happy going through points.

Said Stove R is now at my house with stern instructions to fix it.

Edit for 29 Nov 2011

I thought I'd add a picture of the underneath of the Stove R:

Lamps on Goods Brake Vans

by John Kendall

I wanted to give everyone the benefit of some research I did recently about lamps. This came about after a friend of mine took me to task for brake lamps on one of my brake vans.

It turns out that brake vans on main lines were required to carry 3 lamps. One in the center and 2 side lamps. For single track branches and double track mainline, these were red facing the rear. Less strictly, it seems, the side lamps were supposed to show white towards the front so the crew could confirm the train was intact.

This picture shows what I mean (OK, the center lamp lost its jewel when I was mounting it, I'll have to paint it red):



For multiple track main lines, for trains on the slow line, there was supposed to be a white rear facing lamp on the side of the brake nearest the fast line. The position of this white lamp was such that the crew of a train approaching from behind could tell which line the train ahead was on. Trains on the fast line carried 3 red lamps.

For goods or loop lines, one red lamp was required.

Allingham has a double track main line and will have a branch line. So, as near as I can tell brake vans on the layout should have lamps as shown.

The guys at the Solihull Model Railway Circle provided me with the info. I just modified the van.

MARK FINDLAY, FORMER BR GUARD, has kindly provided his recollections:

Partially or unfitted trains:

These have a brake van at the rear, and always have 3 lamps on the running line, regardless of the type. The tail lamp just shows red to the rear, as is obvious. The side lamps show white forwards at all times (on main lines) at both sides (and the driver would look out of these to help him see if the train was complete). The side lamps show red to the rear on main lines, but they were adjustable in that they had a removable red slide. When the train was in a loop, this would be removed to show white to the rear on the side nearest the running line. This indicated to the driver of any train on the main line that the freight train was inside the loop clear. My memory fails me a bit on the case when on the slow lines of a four-track line, but I think if the train was on a running line, 3 reds would continue to be shown; however other accounts don’t mention this.

Some accounts mentioning showing just 2 red lights in some circumstances, but this did not happen in my day.

Side lamps were always to be removed when going into sidings other than recess.

Tail lamps were always painted white; side lamps either black or white.

Fully fitted trains, including parcel trains where no passengers are carried:
Just one tail lamp shown.
The guard would always ride in the rear cab of the locomotive except for nuclear flasks, where the guard rode in a fitted brake (usually piped only) behind the train, with a barrier vehicle between the van and the flask vehicle. Another barrier would be present between the flask vehicle and the loco (these requirements no longer exist, I believe.) No brake vans or barrier vans are required nowadays.

Passenger and ECS:

In my day, all showed a separate oil tail lamp, even DMUs, except for HSTs with their own high intensity lamps. This requirement was removed for DMUs, which had their own built in rather dim red lamps.

The rule is quoted here:

7.4 Side Lamps

7.4.1 Guards of freight trains not fitted throughout with the automatic brake must ensure that in addition to the train tail lamp, two side lamps are carried on the rearmost brakevan. After sunset or during fog or falling snow they must show a white light forward , but the indication to the rear must be as follows:-

a). On main lines,fast lines and single lines- two red lights.
b ). On slow lines,relief lines or loops adjoining main or fast lines and running in the same direction- one red light on the side furthest away from the main or fast line and one white light on the side nearest the main or fast line.
c). On goods lines or loops adjoining slow or relief lines and running in the same direction - two red lights.
d). On reception sidings - the side lights must be removed or obscured when the train has passed into the sidings.

The above just refers to the sidelights and the aspect to be shown to the rear.. the main red tail light in the centre of the van would remain illuminated all the time of course...The reason for changing the aspects shown to the rear was to avoid confusing a following train or one passing a freight on a slow line or in a loop. The reason for showing white lights forward was to indicate to the loco crew on an unfitted train that the train was still intact and following.

Thanks to Mark for this information.

Re-using Lifted RTR Points

By John Kendall

In my experience it is extremely difficult to remove ballasted track so that it can be reused. I wouldn't re-use any of the track I lifted from my last layout. Best to plan and budget for new track when contemplating a new layout or refurbishment of an existing I think.

I feel strongly that lifting RTR points for re-use is a non-starter. However, an idea I hit on (and I'm sure I'm not the only one) is to remanufacture, say, used PECO points. When lifting the point, the timbers get distorted (but not so it is obvious to the naked eye) so that when relaid, rail vehicles frequently derail. I decided to take old code 100 points, strip them down and rebuild. The stock rails, closure rails and blades are fine. You have to make the common crossings though. Print the PECO point template available on the PECO website (http://www.peco-uk.com/page.asp?id=pointplans) and tape it to a flat surface. Cut copper clad timbers to length and stick these to the template with cheap double sided sellotape.

Now solder the rails and crossing using handmade point principles (Great care must be taken at the "frog" to ensure that the crossing is correctly aligned for both routes. This takes a bit of practice).

Some good sources for this:

1) An Approach to Finescale Track by Iain Rice. Not only does this work provide instruction on how to make points but also a very entertaining history of trackwork.
2) Trax2, comes as a book with CD that lets you print point templates. The book provides step by step instruction on construction of various points.
3) Right Track 10, Terrific Trackwork from BRM. Hosted by Tony Wright with instruction by Norman Solomon.

Read, watch, listen and then do. You will probably find that some techniques work for you while others don't.

Another source for the very ambitious is Templot:

http://www.templot.com/

Another thing I would recommend is that you use the Carrs solders and fluxes. You may get away with electrical solder but I find the 145C solder and green flux to be my preferred medium. (http://www.finescale.org.uk/index.php?option=com_virtuemart&Itemid=56)

The great thing is that you already have the rebate for the blade on the stock rails and the blades pre-made. Making blades is probably the most time comsuming job when building points. The other advantage of course is that you save money by not having to buy new points and furthermore you've stretched your modelling skills as well.

There is one other advantage, you can make the point to any radius you want - I used Trax2 for the templates for this. PECO points have enormous gaps between blade and rail, when you remanufacture, this gap can be reduced. A word of caution - if you use solenoid type point motors (and we used SEEP) be careful not to reduce the throw such that the microswitch or aux switch for frog polarity fails to make. Tortoise type point motors are probably a better choice.

This approach was very successful for Allingham and you can see some of the handmade points in the pictures. I was particularly pleased with the double slip.
