Just saying.
Belfast railway network
With the opening of Grand Central Station in Belfast, this has led to a downgrade in one section of railway, that from Belfast Central Junction to City Junction.
Prior to the closure of Great Victoria Street, trains to/from Dublin ran to Lanyon Place via the old Belfast Central Railway line, departing at Central Junction. However, all internal trains ran via Great Victoria Street, using the Blythfield Curve to do so.
With the transfer of Dublin trains to Grand Central Station, there is no scheduled service between Central Junction (A) and City Junction (B) and the double track has been reduced to single track.

The above titled event will take place on 19th October 2024 in the Parochial Hall, Clonakilty, Co. Cork.

The Cong Canal
One of the lesser known canals of Ireland, also known as the ‘Dry Canal’, due to never having been completed and misinformation around the reasons for same, is the Cong Canal. I came across this recent Youtube Video on the subject, which makes extensive use of drone footage of the area to highlight what remains.
HT to the Greystones Guide for this.
Greystones Archaeological & Historical Society will be holding their monthly meeting on Wednesday 16th October 2024 at 7.30pm in the Kilian Family Centre beside Holy Rosary Church in Greystones.
The talk will be given by Rob Goodbody on the subject of Glendasan lead mines and Ballycorus Chimney.
Admission is €3.
The Boyne Bridge, Belfast
I’m in two minds about this one.
The BBC reports that the Ulster Architectural Heritage Society are intending to take Translink to court in a bid to stop the demolition of the Boyne Bridge in Belfast as part of the latter’s plans to develop the area immediately adjacent to the new Grand Central Station.
Whilst part of me sees Translink mimicking CIE’s status as a property development company with the inconvenience of a public transport network attached, I can’t necessarily see that the bridge requires preservation and if it is worthy of preservation, does it absolutely need to be preserved at that location?

The Bridges of Dublin
The Substation, Dublin Port’s small cultural venue, is hosting an exhibition taking a humourous look at the River Liffey bridges in Dublin City.
Developed by Fergal McCarthy, this exhibition will feature a jumbo version of Fergal’s illustrated portrait of the Liffey and its bridges.
The exhibition runs until early November 2024 apart from 24/25th October.
Train and tram map
I was out and about in Dublin recently and spotted a new map on the DART:

What caught my eye was the marking of the Short Hop Zone at its current boundaries of Balbriggan, Kilcock, Sallins & Naas and Kilcoole. These would be the boundaries that the National Transport Authority are proposing to reduce in geographic area, which would require new maps to be produced.
Open House Dublin 2024
Open House Dublin 2024 takes place between 12th and 20th October 2024. I have reviewed the listing of events and have created a page listing those of IH interest.
Belfast Grand Central Station
Having already opened for bus traffic, it has been reported that Belfast Grand Central Station is due to open for rail traffic on 13th October 2024.
Whilst I haven’t been up in Belfast in the last few months, I have looked at the track layout shown on OpenStreetmap and it looks like Westlink Junction is gone (where the Blythefield Curve joined the line from Central Junction to Great Victoria Street), instead, the line will curve around and run parallel to the Dublin line.
Access to/from the 8 platforms (4 island platforms) will be achieved by a series of crossovers.

Update 14 October 2024. Well, whoever updated OSM got it wrong. There is a junction at Westlink Junction and the necessary crossovers are in place just north of this to facilitate all platform access.
