This project has been talked about for many years, but finally plans have been announced and public consultations are under way.
I'm referring to the idea of turning the Siekierki coal-train line into a proper, electrified, suburban commuter railway, all the way to Konstancin-Jeziorna. [I wrote about this back in 2014!] Now, this project also involves doubling up track from Warsaw all the way down to Czachowek Południowy, to increase throughput capacity for suburban traffic. This therefore means four tracks all the way to Czachówek, meaning that Zalesie Górne, Piaseczno, Nowa Iwiczna and all suburban stations from W-wa Jeziorki northwards will need new platforms. Eight brand-new stations are proposed, with a further two in reserve.
This is how the project, as currently proposed, will look... [Full documentation in Polish – Dobudowa torów aglomeracyjnych na odcinku Warszawa Al. Jerozolimskie – Piaseczno wraz z połączeniem do Konstancina-Jeziornej is here.] Below: a schematic representation of the proposed project.
At the Warsaw end, a new connection to the Radom line will be built from W-wa Włochy, allowing trains approaching Warsaw from the west to swing south directly without having to change direction at W-wa Zachodnia.
This means that W-wa Aleje Jerozolimskie will get two new platforms with three new platform edges. A new station, W-wa Instalatorów, will be built between W-wa Aleje Jerozolimskie and W-wa Rakowiec stations. Extra (island) platforms will also be have to be built at W-wa Rakowiec and W-wa Żwirki i Wigury stations. At W-wa Służewiec station, the current island platform will be removed and replaced by two new island platforms, and (at last!) a new passage under the tracks will be built allowing access to the station from the south (at the moment you either have to walk a 700m detour or cross the track illegally and jump up onto the platform). Several new footbridges are also planned along this stretch, also something to be praised.
W-wa Okęcie, rebuilt in 2016-17, will be demolished yet again and moved further north of its current location, in the form of a pair of island platforms, linked by an underground passage. Something else that's sorely needed is a new station, W-wa Poleczki, between W-wa Okęcie and W-wa Dawidy. This will be built on the north side of the viaduct carrying ulica Poleczki over the tracks and the S79 expressway, and will be hugely useful to folk working in the numerous offices and warehouses that have sprung up around here in recent years.
Another brand-new station that's being proposed is W-wa Krasnowola, on ul. Zatorze, with one island platform; this will be located north of the S79/S2/S7 expressway junction. At present, this will just be a reserve, with a planned option for building it at an unspecified later date. Four new railway viaducts will be needed to cross over the S2 just south of this location.
W-wa Dawidy and W-wa Jeziorki stations, which as long-term readers of this blog will remember were once served by island platforms, will once again become island platforms, straddled this time by not one but two tracks on either side. Ulica Baletowa will go under the railway line; a new viaduct will be built some 400m to the south connected by a new road parallel to ul. Kórnicka and joining the S7's eastern service road on the other side.
A similar story at Nowa Iwiczna, which also reverts to an island platform, and the good news for local residents is that a viaduct is in the plans for ul. Krasickiego, replacing the infamous level crossing there.
It is south of Nowa Iwiczna that the coal-train line swing off towards Piaseczno and Konstancin. This will run double-tracked (and electrified) all the way to a final stop, Konstancin-Jeziorna-Mirkowska. En route, trains will stop at the following new stations: Piaseczno Mleczarska, Piaseczno Energetyczna (adjacent to ul. Puławska - brilliant solution!), Piaseczno Julianowska (serving Julianów), Piaseczno Śniadeckich (the eastern end of Julianów) with a reserve stop at Konstancin-Jeziorna Głowackiego (for the south-west corner of the Las Kabacki forest), past the coal-train sidings, then on to Konstancin-Jeziorna, serving the town centre (on ul. Warszawska), over a new junction where the new passenger line bids farewell to the coal train, which heads off north to Siekierki power station, and finally on to the end of the line, at Konstancin-Jeziorna-Mirkowska.
So that's the new passenger line to Konstancin. Meanwhile, on the Warsaw-Radom line, before it gets to Piaseczno station, there will be another station, Piaseczno Północ, south of ul. Słoneczna, along the route of the new DW721 bis (that phantom road from the stump-end of the new S7's Węzeł Lesznowola that will one day run to Piaseczno. This was once mooted as Stara Iwiczna station, but the DW721 bis made that plan obsolete.
At Piaseczno, a station newly rebuilt and now serving as the end of the SKM lines S4 and S40, the current platforms will be dismantled and replaced with two new island platforms serving the four tracks, and a new footbridge built at the station's southern side.
The level crossing in Żabieniec will be replaced with a viaduct. At Zalesie Górne, the current platforms will be replaced with a pair of island platforms, and the level crossing on ul. Pionierów will be replaced by a viaduct.
The same will happen at Ustanówek and Czachówek Górny, with island platforms replacing the newly built platforms that now lie on either side of the tracks. The Czachówek diamond will remain as is, with just single tracks connecting west to north, north to east, east to south and south to west spurs.
At Czachówek Południowy station, which already has two island platforms serving four tracks, the existing platforms will be extended to the south. The existing level crossing will be replaced by a viaduct 200 metres further south. And here, the four tracks will merge into the two that will carry trains local and express on to Radom via Chynów, Warka and Dobieszyn as they do today.
The upshot of all this track-doubling is that once done, during the rush hours, the line will be able to accommodate one local train every five minutes (!) and one InterCity train every 15 minutes. Excellent!
Public consultations are taking place up and down the line until early June. The full timetable of dates and venues here. (My nearest one will be in Uwieliny, near Zalesie Górne, on 29 May). My fear is an outcrop of BANANAs (Build Absolutely Nothing Anywhere Near Anything), the radical wing of the NIMBYs (Not In My Back Yard). I can see this around the project to link the Radom line from Warka to Grójec. Of the 12 variants put up for discussion, all 12 have been shouted down the local communities, including here in Chynów.
Even if the whole Konstancin rail project goes ahead, my experience (S79, S2, S7, Warsaw-Radom modernisation, all covered on this blog) suggests that it might be 2033 at the earliest before we actually see this completed. The tender for the detailed design is not to be announced until the second half of 2025. From then, another five years could pass before construction work begins in earnest, so provided there are no delays, 2033 is possible.
