Mike T Posted December 29, 2009 Share Posted December 29, 2009 Hi Guys The following was buried amongst an old RMweb thread on Scottish Signalling and provides information on how I would go about making such a 'signal'. The original was for an N Gauge layout but the principle applies to any scale. See here for example of 'signalling' associated with RETB http://www.railsigns...etb1/retb1.html "RETB Stop board at the north end of Ardlui station. 'Drivers in possession of long section token may proceed.' (August 2007)". See original image at http://www.scot-rail...to/scaled/1049/ This is the type of 'signal' you would need to make. The dimensions of the stop board are as follows - NB it is a large board at 900mm wide From this you should be able to guesstimate the dimensions of the TPWS LSI - the black board with blue light, and the long section board. I would use brass wire for the posts and make these functional to supply the power to the LED. The boards themselves should be easy to knock up in any graphics or CAD package even mspaint!. A blue surface mount LED should be small enough in 2mm - try Ebay. This is how I would go about making the basic 'signal' Mark out the size on graph paper and pritt stick to 10thou doubled sided PCB offcut (obtainable from C&L Models at shows) Cut through the paper to mark out the PCB - oops I slipped! Remove the paper then file to the lines The basic board and LED - this is the only blue one I had to hand and smaller are available. Gap the PCB The LED soldered in place A quick test! The first 0.5mm brass wire soldered in place and getting ready to line up the second one The finished board in a LED tester ready for paint and graphics. Hope this helps.

Mike Turner Posted November 1, 2010 Share Posted November 1, 2010 Hi Guys After a discussion at the Merseyside show over the weekend I thought the following may be of interest for anyone thinking about an RETB Scottish layout... The first RETB controlled line was Dingwall – Kyle in the Far North of Scotland, and was commissioned using a very high frequency (VHF) mid-band II radio system in July 1984. The Far North Line (FNL) to Wick and Thurso commissioning followed in December 1984. Initially, control of these routes was from Dingwall, and the intention was that the Inverness re-signalling scheme would include the Inverness – Dingwall section. However, RETB was extended to Inverness , the radio system upgraded to mid-band III, and control moved to the new Inverness Signalling Centre in August 1988. The FNL routes are: a. Ness Viaduct ( Inverness ) – Dingwall b. Dingwall – Kyle of Lochalsh c. Dingwall – Georgemas Junction d. Georgemas Junction – Wick e. Georgemas Junction – Thurso. Following the RETBs success with the FNL, the radio system was upgraded to VHF mid band III, and implemented on the West Highland Line (WHL) in late 1987. RETB was introduced on the WHL in three phases, and is controlled by two signaller workstations in the Banavie signal box, which also controls the Caledonian Canal swing bridge. WHL RETB operation started firstly on the Mallaig section on December 7, 1987. Helensburgh Upper – Crianlarich – Oban converted on March 27, 1988 and, finally, Crianlarich – Fort William Junction on May 28, 1988. The ‘South’ workstation controls Helensburgh – Upper – Crianlarich – Oban. The ‘North’ workstation controls Upper Tyndrum – Fort William Junction – Mallaig. TPWS was added as an overlay system in 2003. Regards Mike Link to post Share on other sites More sharing options...
tractor_37260 Posted November 1, 2010 Share Posted November 1, 2010 TPWS was added as an overlay system in 2003. Regards Mike Hi Mike Interesting post - especially the date of the TPWS addition. Any ideas of the font used on the signs ? aware it states std road sign font - but what's that Plan/hope to make some up in MS PP. Totally OT but any updates on the Class 104 cab etches etc being made available ? Regards Ken Link to post Share on other sites More sharing options...

RMweb Gold big jim Posted May 26, 2011 RMweb Gold Share Posted May 26, 2011 very interesting, first time i've found this thread, does the led flash once the "token is accepted" as such on the cambrian once you get the token the blue light flashes to tell you the tpws is set for you to go but it does time out (2 mins i think) i did have it at newtown one evening where i'd got the token but in the mean time the rhtt cannon played up so the operator got down to have a look, just as i aproached the board the light stopped flashing but luckily i stopped in time with about 1/2 loco length to spare!!
