Waterford Line Mini-CTC

panel is located at Waterford West and as this interlocking is not included in
the new system, there are two signalmen at Waterford West signal cabin. One
controlling the Waterford Line CTC and one the mechanical interlocking there.
Unlike the Galway Line where the system terminated in a terminal station, the
The new panel at Waterford West incorporated the ‘traffic direction’ switch for Ballyhale (bottom left), while top left are the traffic direction indicators. The status of the track circuits on the western half of the Waterford West interlocking are indicated on the panel by red (occupied) or yellow (unoccupied) lamps. The position of four mechanical signals is also indicated by red and green lamps instead of the more traditional miniture arm in a case. Newrath No. 1 level crossing is incorporated into the Waterford West interlocking and the ‘Section Signal’ for Ballyhale, No. 42, will not display a proceed aspect unless the level crossing is closed against the road. Similarly the ‘home’ signal from Ballyhale No. 4 requires the gates to be closed to road traffic.
In the months preceding commissioning, sidings at Athy, Carlow and Thomastown and their associated signals were taken out of use and new colour light signals and equipment cases were erected. In the case of Carlow, removal of the turnout, No. 18, at the north end of the freight yard converted a loop into a dead-end siding and necessitated a change in working. The 14.05 Waterford-Drogheda empty bulk cement train regularly crossed both the 15.05 Dublin-Waterford and the 14.40 Waterford-Dublin passenger trains in Carlow. Following the change, it arrived directly into the freight yard first and, after both passenger trains departed, it had to propel back out of the yard towards Muine Bheag before resuming its journey.
From Wednesday 14 April, before the main closure, Thomastown ceased to be a crossing point with all points disconnected before subsequent removal. During this period, passenger trains ceased to call, with passengers conveyed by road to and from Kilkenny. The 09.30 Dublin-Waterford and 13.10 return operated to and from Kilkenny only, as did the Fridays and Saturdays-Only 16.30 Dublin-Waterford.
END OF THE MECHANICAL SIGNALLING
was a complete line closure from 19 to 28 April to allow points to be renewed in
stations and commissioning of the new signalling system. Passenger trains were
substituted by bus to and from Newbridge. Freight trains were cancelled, except
the Drogheda-Waterford cement trains, which operated via Wexford. The line was
closed after the passing of the up 0720
Three new turnouts were installed in Athy, three in Carlow, and two in Muine Bheag and old points and turnouts removed. Thomastown ceased to be a block post and all points and signals were removed. The track through the station had been excavated and re-laid with CWR on concrete sleepers in February and is on the up side on the station building side.

Track circuits are used in station areas, with axle counters for the single line sections between stations. Points and traps for sidings are automatically moved from the reverse to the normal position after a train has passed. Kilkenny, which was previously a power signalbox with colour light signals covering the station area and the sections Muine Bheag-Lavistown, Lavistown-Kilkenny, Lavistown-Thomastown and the triangle at Lavistown, was incorporated into the Mini-CTC system. These sections all previously used track circuits but Muine Bheag-Lavistown, Lavistown-Kilkenny and Lavistown-Ballyhale sections were converted to axle-counters. Other than adding a ‘2’ in front of existing point numbers, there were no changes made to signals formerly controlled by Kilkenny. Waterford West takes over monitoring Ballyreddin AHB crossing from Kilkenny. Kilkenny one-control-switch panel is no longer available to control any lines, as it cannot interface with Mini-CTC. The track circuits between Cherryville Junction and Athy had been previously replaced by axle counters. In Waterford West, new two-aspect colour light down distant, down outer home and up section signal protect Newrath No. 1 and No. 2 level crossings but there is no change to the semaphore signalling through these gates on the Limerick line.
