Re: Extracting coach wheels from Hornby Gresley suburbans

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...

Re: Any Wheel and size!

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

Re: Can I drive a Seep motor from a lever frame?

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...

Re: Chassis kits for CSB

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...

Re: Chassis kits for CSB

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...

Re: Movement detector?

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...

Re: Chassis kits for CSB

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...

Re: Modern Era Concrete Track

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...

Re: Modern Era Concrete Track

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...

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.

Re: Modern Era Concrete Track

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.

Re: Rail codes

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, ...

Re: Catch Points

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.
