Slovakia just have a part of the network AC. Now there is reconstruction of main line Bratislava - Zilina - Kosice for 100km/h to 160km/h. When there are investing to new railtrucks, tunnels, stations... it is not high added cost investing in AC. There is map:

Railway from Dobova to Ljubljana is double truck, but made by old standars, and speed is 80-100km/h. If anytime there would be reconstruction for 160km/h or more, it is better to make it with AC. I remember, one Belgian railwayer told me that EU fondations can be used only for railways with AC 25kV. Now, for example, Bulgaria make new double truck railway to Turkish border for speed 160km/h and proposed 200km/h, with EU money, and Slovenia?

- Rebuild all sub-stations, and above all, make sure that the power grid can
feed it properly : DC current can be "fabricated" from a symmetrical input of
3-phase power, but an AC catenary can only be fed by one phase of the
power grid, creating a severe unbalance that only very strong grids can
accept. Will it be the case in Slovakia ? Even the french one had problems
when the TGV substations started working in 1980...
- Rebuild most of the signalling system because the track circuits used with
3 kV will NOT work with AC electrification.

As I said above, Belgium and France have already considered that option and
both withdrew because of the sheer costs. I doubt very much that Slovakia
will be able to bear them, unless there are only a few hundredth km to convert. So I'll believe it when I'll see it.
Slovakia has 1556 km of electrified standard gauge railways:
2.3 km - 15kV 16,7Hz AC
737 km - 25 kV 50Hz AC
816 km - 3kV DC
There are also wide gauge and narrow gauge electrified railways, but we can ignore them.

3 kV DC lines will be converted during modernisation of Va and VI corridors. This complex modernisation basically means there will be built new railway at the site of the old one, in central Slovakia on Va corridor it will be mostly brand new railway and the old route would be demolished because it's not possible to reach needed speed on present railway (it must be at least 160 km/h, but new lines will be ready for 180 - 200 km/h).

For now there were modernised only lines where AC was used before, but in 2015 there should be already converted first DC section from Pchov to Žilina. Of course it will take many years until whole network will be unified. Major part of the conversion will take place between 2014 and 2020 thanks to EU money. In the meantime railways are going to buy new multisystem locos and EMUs and upgrade some present DC rolling stock into multisystem AC and DC to avoid problems during conversion.

I can't see the map in Rail Serbia's post so here is another one which will help to understand it:

Slovenia: EUR 32.6m loss of Slovenian Railways in 10 months

Between January and October this year, Slovenian state-owned railways recorded a net loss of EUR 32.6m, SEEbiz reports.

Cargo traffic with Slovenian Railways dropped by 30% in the mentioned period. Compared to the first ten months of 2008, the company's revenues decreased by EUR 31.9m. These results are slightly better than the forecasts for 2009, the supervisory board of Slovenian Railways announced.

Consequence of:
1 - incapable leadership of S (state railways) and their persistent unions
2 - foreign operators (mostly Austrian) are taking over freight business
3 - recession

nothing new. but I would not agree that SZ's inability to defend against competitors is the competitors' fault.

Actually it is. Competitors are small and efficient and they easily take freight from old, big and inefficient state organisation, even if it has new rolling stock. This year foreingers took about 7% of total freight and next year almost double of that is predicted, even if recession slashed total freighttraffic to only about 75-80% of previous year value.

In Slovakia we invented an easy way how to defend evil Austrians who want to enter our railway market. We don't allow any Austrian locomotive to enter our territory deeper than to Bratislava. But, our national cargo operator still has to compete with some evil private operators, how sad...

S need serious reorganisation, there are so many problems with them, that they would bankrupt years ago if they wouldn't be so heavily supported by the state. But also this support is slowly diminishing.

on the other hand, SR comes to Budapest with their locomotives

btw, i salute to limiting foreign strong operators to do whatever they want under mask of free market

(It's ZSSK, SR just maintains railways and stations.) Some Hungarian locos can be operated in Slovakia, but except some border stations they aren't.

You should apply for a job in our Ministry of Transportation or in some of the railway companies.

I don't. In railway sector this means that old inefficient state railways don't improve their services and are even greater burden to state budged and taxpayers pocket. Slovenian S is really the right case. Constant changing of company leadership, big and powerful unions, who would like to get more and more money for less work and indecisive government makes S traffic services more and more unappealing therefore losses are bigger and bigger.

Foreign operators work in a modern way and don't eat my money (as a taxpayer).

National cargo operators should not receive public money. If they get something to survive the crisis this can be accepted, but not anything else. If they need money during economic growth then something is really wrong there. On the other hand, they should pay full price for using railways. However, they shouldn't be expected to pay all maintenance costs, passenger trains also use the railways.

I agree with you, but people in charge don't do much about it.

Slovenia: Employees of Slovenian Railways ask their representatives to leave

Employees of state-owned Slovenian Railways asked their representatives in the companys management board to resign.

Workers of the rail operator accuse their representatives of acting against the interest of employees. It is reported, that the representatives might be responsible for creating a list of people, that were sent on a temporary leave.

Workers with more than 20 years of experience have been put on hold, while their posts were taken over by people, who will do the same work for a higher salary, employees of Slovenian Railways claim. It is believed, that the new workers were chosen based on a personal interest of the representatives, Limun reports.

Any news of the new Koper-Divaca railway? It will have one or two tracks? As far I know only one, with part of the traffic routed via the existing line, but other sources say it will have two tracks.

It will be single track, but the alignment is built with reservation for a second track if needed. 21 km out of 27 will be in tunnel!
