I have not tried these specific bogies, but most Hornby (and Bachmann) bogies can be flexed enough to get the wheelsets in and out. A thumbnail each side between axlebox and wheel has always done it for me. If you can't get the old ones out then you won't get the new ones in. Although while the whee...

That should just be the minimum width on the drawing, a lot of manufacturers went for the maximum.

The profile is in the Standards digest.

The simplest solution is to use a Capacitor Discharge device designed to be the interface between a simple switch, ie the microswitch on the lever frame, and a solenoid type point motor. MERG has kits for this, PD3 at approx £9, that can link 2 levers to up to 4 points, eg 2 crossovers. An alternati...

Is the second video meant to be this one?

I said the opposite. Of course the same laws apply. There is not a separate, different case. But when calculating the effects of moving vehicle body inertia, the value of "a" in F=ma is zero when stationary and only increases gradually as the vehicle speed increases. That formula does not...

So you do want to rehash it :) One if the "what for" points is that making chassis construction simple, fast and impossible to get wrong, would likely steadily increase the membership of the Society tenfold. Maybe even start a trend of there gradually being easy to manufacture RTR P4 equip...

Unless you operate in the dark light dependent resistors (LDRs) work from the ambient light and fit nicely between the sleepers detecting anything passing over putting them in the shade. The MERG pocket money kits have these detectors for £0.88 each including an LED for the indication. The circuit o...

Obviously sufficient weight of the loco will force all the wheels down on to the flat portion of the track, by forcefully bending the wire against its alternating tendency. But that means the individual wheel weights will be increased or reduced incorrectly for optimum track holding. Andy, do you r...

Just to follow up on this, my drawing of Rhodesia Railways sections includes 14 varieties and I have summarised the key dimensions in the attached pdf. Also attached are 3 scans from the drawing. (some sections are to faded to scan adequately). Note the BS80LB A is the same rail used for the Docklan...

I've never encountered or heard of f/b inclined rail through turnouts /crossings on mainline railways either new or old. Colin Some pertinant information here. http://www.norgrove.me.uk/GWRtracknotes/letter-p1.pdf and http://www.norgrove.me.uk/GWRtracknotes/letter-p2.pdf http://www.norgrove.me.uk/G...

What is the relationship between the use of wooden and concrete sleepers in S&C to the use of vertical or inclined rail in S&C? Are all FB S&C with wooden sleepers vertical and all concrete S&C inclined – or is it just not that simple? Not that simple, all of the inclined FB predati...

Why not buy some more of the Exactoscale ones?

Inclined rails were standard on British main lines in the bullhead era throughout both plain ttrack and S&C. This practice continued with the first generation of flatbottom. S&C with vertical rail was introduced when the gauge was reduced from 1435 to 1432 (Misguidedly somtime in the mid 60s...

I don't have any FB track layed, just some samples I got some years ago. Shown in these Pics. As can be seen the C&L sleepers are Dow-Mac, the Exactoscale fastrack are Costain. Peco also do concrete sleepers and some poor clips of no identifiable type in their individulay range but they are not ...

Hi, For the main track, I think I will be looking for concrete sleepers, Pandrol clips, and code 82 FB rail. I may have a point and crossing which will probably be wood sleepers. I’m trying to work out the best track system, Exactoscale looks the most promising. I’m a bit confused around the descri...

All the twist rails I have seen the twist occurs between two sleepers, not over several sleepers. Between CWR and turnouts there is often an expansion joint on timber which may be what you are thinking of.

As the rail code represents only the height the other key variables can be well off, especially when using a rail in a scale it was not intended for. From a model viewpoint head width is important for correct appearance and foot width also to some extent. for the prototype drawing may be locatable, ...

Hi Nick, Welcome to the forum. Bill Bedford does CSB chassis kits and this one is GWR http://www.mousa.biz/fourmm/loco/frames/gwr_loco_frames4.html High Level does hornblocks and bearings designed for CSB as well as Jigs for using them, but I.m not sure if any of his kits are suplied with them. http...

See for example the Dave Jones threads on RMweb. It has to be done properly.

I'm sure the committee will consider this but lets keep this on-topic to Colin's request and not wander off into Society policy.
The only professional model maker I'm aware of is Rocar.

and, in this case the lack of a release crossover and run round facility in the bay.

Noel. Am I right in thinking that because the catch points are controlled by the Box they would not have hand operating leavers attached to them as well {due to them being tied in with the interlocking of the signaling}? Dave Yes you are right, no hand levers on interlocked trap points. Note that o...

Sorry, I didn't look at that diagram closely and, of course, a word search doesn't find that.
That certainly suggests that the one on 26 may have remained in use. and the use on 16 certainly suggests use of the siding by passenger trains at some time.
