The railway is a
single track line with
passing loops at , , , and halt. There is also a loop at , which is normally locked out of use as a stabling point for engineering trains. As with any single track railway, there are strict rules managing the movement of trains to prevent more than one entering a section. The line is managed from a single "
Control" office at
Boston Lodge Works, which also performs the same task for the
Ffestiniog Railway. Control is responsible for the safe and efficient operation of trains, logs train movements on a train graph and acts as a single point of contact in emergencies. A system of
tokens is used to control train access to single line sections. Communication between train crew and Control always occurs using a landline at stations. There is no in-cab radio system and current regulations forbid use of such whilst in motion. As a backup system only, the guard carries a company
mobile telephone for use in an emergency. This is not a primary system as cellular coverage is intermittent over the length of the line.
His Majesty's Railway Inspectorate, the organisation responsible for safety on British railways, insists on landlines as the main form of safety critical communication.
Signalling No. 87 passing the bridge over
Afon Glaslyn. The WHR at present has two systems for block section control. The original
Staff and Ticket system is slowly being phased out in favour of a more flexible
Electronic Token System (ETS).
Staff and Ticket To enter any section of line still controlled by Staff and Ticket, the train crew must obtain permission from Control and the relevant
token. Each section of line is a token
block section. The WHR uses the traditional Staff and Ticket system in which trains can either be issued with the section token staff or a numbered ticket. Tickets allow multiple trains to pass through a section in one direction one-at-a-time. The Controller advises the train crew which method they will be using. Tickets are kept in a locked box opened by a key on the token staff. This means the last train must use the token staff to pass through the section, so it can be used for trains to travel in the opposite direction. For additional protection, both the footplate crew and the guard must see the token or ticket before the train can depart.
Electronic Token System One of the disadvantages of the staff and ticket system is that it is very inflexible. If a locomotive fails in a station, for example, a token staff may be at the wrong end of a section and will have to be moved by road. This situation does not occur under the Electric Token System (ETS), a more advanced system in which tokens can be obtained at either end of a section from a token instrument. ETS has been used on the
Ffestiniog Railway for many years and the FR Co. were anxious to obtain enough ETS instruments to equip the WHR. After a long search, sufficient ETS equipment to operate the entire railway has been obtained from the Irish railway company
Iarnród Éireann. The equipment became redundant after Iarnród Éireann modernised its signalling systems in the early 2000s. During the reconstruction of the WHR it was believed that installing cabling along the track bed would not be needed and the decision was made not to install cable ducts under any of the crossings. As a result traditional ETS as it was originally designed could not be installed without considerable civil engineering to install new ducts along the railway. Subsequently the FR Co. developed a more modern alternative method of connecting the ETS machines over the internet called microETS.
Shunt Token At all intermediate stations an additional "Shunt" token is used to allow shunting to take place (such as a locomotive "running round" a train). The shunt token can only be withdrawn (used) with permission from Control and if there are no trains approaching the station in the adjacent single line sections. Withdrawing the token prevents other trains from entering the station.
ATOTP The majority of the points at passing loops are operated automatically using the Automatic Train Operated Trailable Points (ATOTP) system, rather than a manually operated lever or point motor. These work via a weighted lever and
hydraulic ram located in a cabinet to the side of the points. When a train is entering a station the weight holds the points in the normal position, allowing a train to pass over without a traditional
facing point lock (FPL). When a train has obtained a token and has permission to leave the station loop it trails through the points, pushing them into the desired position, and causing the weighted lever to be lifted. In order to minimize damage to the points and wheel flanges of the rolling stock the hydraulic ram is used to slowly lower the weight back into its resting position over the course of 15–18 seconds.
Cae Pawb – The Cambrian crossing Just outside Porthmadog, the railway crosses the
Network Rail-owned
Cambrian Coast Line using a
flat crossing. It existed on the old Welsh Highland Railway and was the source of much conflict between the old company and the
Great Western Railway over the cost of WHR trains using the crossing. On the modern WHR, the crossing is called Cae Pawb. Cae Pawb means "everybody's field" and is a reference to the nearby field of allotments. Information, from the engineers involved, is that the Network Rail line crosses on solid steel billets to the same head, foot and height measurements as the adjacent standard gauge rail, but that the narrow gauge crosses on rail of a similar section which is joined on either side in succession to 80 lb/yd (36 kg/m) rail and then to the normal 60 lb/yd (30 kg/m) rail used for the narrow gauge. Cae Pawb is at the north-western end of the Network Rail
Harlech to
Porthmadog signalling section, which is controlled from
Machynlleth Control Centre. Standard gauge trains are protected by signals and wide-to-gauge trap points on the WHR line, which are interlocked with the standard gauge
European Rail Traffic Management System (ERTMS) signalling. The crossing is activated locally and ERTMS automatically gives permission for WHR trains to cross provided the standard gauge section is available. A crossing controller operates the crossing when passenger trains are running, with operation at other times being carried out by the train crew. A set of replica white wooden crossing gates separate the narrow-gauge line from the standard gauge track and continue the Network Rail boundary fencing. They are left open when a crossing controller is present. The gates open inwards to prevent them blocking the standard gauge line. A replica signal box was constructed for this crossing but has now been installed at Pen y Mount to control the junction with the Welsh Highland Heritage Railway.
Porthmadog cross-town link South of the Cambrian crossing, WHR
cross town link trains move direct to Porthmadog Harbour, where passengers alight. At Harbour Station there is a platform between the Welsh Highland and Ffestiniog lines so that passengers may transfer from one train to the other. There are also the usual facilities including a respectable eating house.
Timetable Historically, the WHR was split into two operational sections: •
Dinas to
Beddgelert and
Beddgelert to
Porthmadog (using present day form) For the 2009 timetable operation, a "two set" operation was employed, with rolling stock being based at Dinas. During the year, operations were extended from Rhyd Ddu: first to Beddgelert on 7 April 2009, and then to Hafod y Llyn on 21 May 2009, site of a small halt on the original line. Although passengers could board and alight at Hafod-y-Llyn, its remote location meant that it could only be accessed by self-sufficient walkers and cyclists as there were no parking or other facilities at the halt and the platform was very short. It closed when was opened in 2010. The Festiniog Railway Company had, at one point, planned to open the entire railway in 2007. Delays from government processes, an epidemic of
foot-and-mouth disease and funding restrictions meant that the opening was repeatedly delayed, with the full opening not happening until 2011. The line could not be opened to Beddgelert until the track left the national park at Pont Ynysferlas; this restriction was imposed by the Snowdonia National Park Authority to be sure that the railway really meant what it said, but this suspicious attitude lost the railway a year's income from Beddgelert. From the end of May 2010, the line was extended a further to . Shortly thereafter the railway announced that as it had approval for service by the Safety Directorate of the
Office of Rail Regulation (ORR), the remaining section would be completed before the end of September 2010. The cause of this sudden rush was the transition from legislation enshrined in the Railways and Other Transport Systems (Approval of Works, Plant and Equipment) Regulations 1994 (ROTS) to new legislation enshrined in the Railways and Other Guided Transport Systems (Safety) Regulations 2006 (ROGS). This should have happened in 2006, but heritage railways gained an extension of the transition period to 1 October 2010. It was foreseen that this change in regime would bring additional costs to the railway, so it was decided to complete the line before that date. A minor delay was incurred by the necessity to build a new culvert where the new Porthmadog A487 bypass road was being built. Following the visit from the ORR on 15 October 2010, approval was given for passenger operation. On 30 October 2010 the first passenger trains, departing from Caernarfon to Porthmadog and return, were operated for the benefit of sponsors of the project. The commissioning of the ERTMS signalling on the
Cambrian Line was completed during a possession from Harlech to Pwllheli between 24 and 27 October. As a result of the A487
Porthmadog bypass works, the Ffestiniog Railway was severed just east of Minffordd station from 3 January to 16 February 2011 to build a new bridge. Therefore, the regular winter FR trains were scheduled to operate from Porthmadog to . The first through services between Caernarfon and Porthmadog Harbour station began on 19 February 2011, with regular services recommencing from 27 March 2011.
Whole of line operations Although, with completion of the main track laying it is now possible to run trains from through to , • On 10 June 2018, whilst hauling a passenger train, locomotive 143 was derailed near Clogwyn y Gwin South foot crossing due to the failure of part of the suspension of the front bogie. There were no injuries amongst the 74 passengers and seven staff on board. • On 16 April 2019, the diesel locomotive
Vale of Ffestiniog passed a signal at danger and entered a single line section without authority while travelling light engine from Dinas to Porthmadog. The locomotive did not have sufficient brake force to stop on the steep downhill gradient through Beddgelert, as a result of in-house modifications to the brake system and poor adhesion conditions. There were no injuries, and no damage was caused. • On 19 December 2021 a derailment occurred on the bogie of the fourth passenger coach (no. 125), just after crossing Brynyfelin River Bridge. The line was closed for two days to recover the train. == Stations ==
