In Thailand, Westinghouse installed location cases with double skinned doors, sides and roof to concentrate air flow and cooling, that was with relays.

Have you looked at the Railway Heritage Register Partnership. This includes details of carriages and has a link to another database of locomotives. I cannot vouch for the accuracy of the information. https://www.rhrp.org.uk/

According to the General Appendix to the Rule Book, the distance is 13 miles 45 chains measured at the Water Tower Crossing. Note this is an internal document, not for publication.

Might I suggest you go back just a few comments on this thread to #452 where Belberpete explains how the Ff&WHR operates today. If you want to join a train at Minffordd and travel to Dduallt, the guard will sell you an appropriate ticket. Essentially this is no different to pre Covid. Belperpete...

Jointless Track Circuits have been in use since at least the early 1970’s, not necessarily in universal use but applicable to both a.c. and d.c. electrified lines. The use of axle counters eliminates the need for insulated rail joints.

Taking a different course, the Ffestiniog Railway introduced a computerised booking office at Harbour station about 50 years ago using a system designed by Brian Bushell. The system lasted for about forty years but has since been replaced by commercially available software, essential for on-line...

Hereford is another example of a bay platform that is unused due to the layout at the up (north) end of the station. At least departure signals were added on the island platform a few years ago so that GW and West Midland services towards Worcester could depart without having to reverse via the...

One you may have missed, and what an event! Not just celebrating Rail 200, the Ffestiniog Railway is also celebrating its Platinum Jubilee, yes 70 years since reopening in 1955. With an event spread over four days from 19th to 22nd June 2025, there was a great deal of variety on offer. Included...

Much of this discussion is fascinating. It might be worth remembering that all this will have been though through: During the pan European development of ERTMs (incorporating ETCS and GSM-R) Some twenty plus years ago. The U.K. was represented on the steering committees by what is now Network...

Some Siemens point machines are designed with combined motor and detection over the same four wires. On a Contract in Finland with WESTRACE interlocking and Siemens point machines a complex relay interface had to be designed that cost a small fortune. Presumably SIMIS takes this into account in...

Just a quick reminder. Where references are made in this thread to Siemens, this is the German company before they bought out Invensys/Westinghouse in the U.K. in 2013. One of the reasons Siemens won the Bournemouth and Portsmouth Contracts was to enter the U.K. market, but using their own...

Agreed, however these would probably be more to tell the driver to proceed linked to the timetable/headway rather than a block marker, although I don’t know if the Victoria Line control system could do that. Other mass transit railways have similar indicators either as a pseudo signal or a count...

ETCS is just another Automatic Train Protection (ATP) system. The first ATP system in the U.K. was commissioned on the Victoria Line nearly 60 years ago. The Victoria Line has never had a back up system of lights on sticks. OK that was a brand new line, but the same principle applies to the...

It’s also easier to interface Westcad with other digital systems such as Computer Based Interlockings (e.g. SSI, Westlock, Westrace, Smartlock), legacy remote relay based Interlockings using Time Division Multiplex communications and train describers. There are probably other digital interfaces...
