Only a leader like Chavez has the concern for the welfare of the people and country to start and initiate something like this. A conservative, neoliberal leader would never attempt something like this or would set up some crony sweetheart deal with a foreign multinational that would produce a sub standard product.

Nice to see that trains are being improved in Venezuela in such a good way.

I´d like to travel to Venezuela to check what does the people think about Chavez and all the political situation in situ. Sometimes i have the feeling that i´m only getting one side of the history through the media or even through venezuelan forumers i have met on the net or here in Europe...most of then living outside venezuela i must add.

RAILWAY TRANSPORT SYSTEM OF THE CENTRAL REGION: CARACAS TO CUA CONNECTION
Employer: IAFE - Instituto Autonomo de Ferrocarriles del Estado
Contractor: Consorcio Contuy Medio with Impregilo S.p.A. Lead Partner (35.40%)
Construction period: May 1996 - December 2007
Work description:
The Railway Transport System of the Central Region concerns the connection between Caracas, the Tuy Valley and the Valleys of Aragua, Valencia and Puerto Cabello, with electric trains for passenger and goods transport on short and long distances. The double track electrified railway line Caracas - Cúa Section is only the first phase of the Railway Transport System linking Caracas to the Tuy Valley. It will reduce the traffic congestion of the capital by connecting the metropolitan area to a large urban developing area.
The contract includes also the following activities:

* executive design of the whole rail line;
* civil engineering works;
* supply of superstructures;
* supply and installation of equipment and systems;
* personnel training for plant operation;
* starting of operation of the Integrated System.

This first phase rail line starts at Coche, southerly to Caracas, where a new multipurpose interchange railway station will be constructed; this included a rail station, the Mercado subway station on line 3 and the Western station for urban and interurban transports. Starting from this junction the 41.4km long railway line extends towards the Tuy Valley, crosses mountainous zones with 24 tunnels (overall length 20.1km), the fairly flat terrain with 13km of embankments (earthmoving works total volume 4,500,000m³) and 28 bridges and viaducts (total length of 8.3km), therefore permitting a fast trouble-free route.

Overall contract works are divided into the following three main sections:
Section A - Civil Works relevant to lots 1, 2, 5 and 6 (section overall length 27.6km), to be executed by the Consortium lead by IMPREGILO S.p.A with a participating share of 36.40%.
Section B - Civil works relevant to lots 3 and 4 (overall length 14.7km) to be executed by one consortium partner.
Section C - Supply and assembling of plants, equipment and installation for the overall line (to be executed by IMPREGILO S.p.A as sole contractor).

Three other stations are foreseen to meet the demand for passenger transport, together with yards and workshops for track material maintenance and transfer and clearing of goods.
The contract foresees also the construction of a multipurpose interchange station, the connecting rail network to Caracas together with the operation yard and the area destined to military forces.
Besides what above mentioned, the Integrated System includes:

* Signalling and control system made of three under systems: automatic protection system, control and supervision of trains operation;
* Telecommunication System principally made of a primary transmission under system (through optical fibres), of a Control Centre from which Integrated System operation can be wholly monitored, and of the various other under systems (telephone system for train operation, customers announcement, radio telecommunication on trains and central control yard);
* Passenger trains made of two electrical multiple units, each composed of four carriages (two locomotives and two towed carriages).

Main technical features of the civil works of Section A
The following main structures were executed:

* Nine tunnels, for an overall length of 10km, with an excavated cross section of 88m².
* Fifteen viaducts (overall length 5.88km, wideness 10.20m), being of double cells viaducts type (total length 4,800m) or steel girders and concrete deck viaducts type (total length 1,250m).
* The four Caracas, Charallave Norte, Charallave Sur and Cúa stations.

The construction of the new rail line had also required fixed protection screenings (total surface 34,000m²), together with more than 24,500m of anchors and bars, and 88,500m of tie-rods (30 to 45tons).

Main features for electro-mechanical supply and assembling of Section C
The line will have a double track with international gauge of 1.435m. The UNI 60 type racks, equivalent to UIC 60 type, have a weight of about 60 kg/m and max. loading capacity of 22.5t per axis, for a total quantity of approx. 11,100tons.
Contact line included overhead conductors and catenaries for about 82km, together with masts and special supports in tunnel sections. Disconnecting switches of the electric power supply lines are also included.
Electric power supply and signalling included 40km of cables in raceways along the line and 33 insulated coupling boxes together with low charge disconnecting switches, plugs and 500W transformers.
The supply of eight multiple electrical unit, made of two locomotives and two towed carriages, is foreseen, for a total capacity of 1,094 passengers, of which 400 being seat. The maximum speed during operation will be 100km/h.
Control system mainly consisted of a control centre, four peripheral transit terminals and four peripheral power supply terminals.

Main quantities:
Open-air excavations works (soil and rock) 4,525,000 m3
Embankment 1,900,000 m3
Concrete Works 160,000 m3

RAILWAY TRANSPORT SYSTEM OF THE CENTRAL REGION: PUERTO CABELLO TO LA ENCRUCIJADA CONNECTION

Employer: IAFE Instituto Autónomo de Ferrocarriles del Estado
Contractor: Consorcio Grupo Contuy, with IMPREGILO S.p.A. Partner (33.33%)
Construction period: July 2002 - April 2008
Work description:
The section Puerto Cabello – La Encrucijada (Cagua) is part of a more multi-modal and articulated transportation network of freights and passengers. It will encourage, through an integrated way, the various transport requirements and modalities through the creation of commercial centres and logistic hubs, therefore to be considered as meeting point of transports on wheels, rail and maritime transports (Interports). During the first stage of works, the above said section will connect the principal port of the country (Puerto Cabello) to the industrial, agricultural and food poles of Valencia and Maracay. The next step of the project will be a rail connection between the cities of San Juan de Los Morros, Calabozo and Cabruta, which is the principal port of the river transportation network Orinoco–Apure. This new rail line will be connected, in the next future, with the rail line section Caracas–Tuy Medio, which is part of the Central Region Railway Transport System.

The new rail line network, which develops for approx. 109.81km, crosses the mountainous section of the route with 15 tunnels (total length 27.97km). Sections concerned by embankments are more than 67.23km in length, mostly in semi-hilly areas (earthmoving works volume over 14,500,000m³), why bridges and viaducts are more than 78 (total length 14.61km), allowing therefore a direct route without any interference. The new double track rail section design followed the international standards, with international gauge of 1.435m allowing a maximum speed comprised between 140 and 180 km/h.

The contract included either the executive design of both line plants and installations together with the rail systems and the execution of the civil works.
In order to meet the passenger’s needs it has been foreseen the construction of seven rail stations, why for goods and freight services (supply, distribution and commercialisation of goods) as well for rolling stock maintenance service specific warehouses and workshops will be constructed.

Main project technical features relevant to the project civil works
The project foresaw the construction of the following structures:

* Fifteen tunnels, for an overall length of 27.97km, having an excavation cross-section varying from 86 to 104m².
* Twenty-six bridges and fifty-two viaducts, for an overall length of 14.61km. Bridges structures are made of steel beams with an upper concrete deck.

The construction of the new rail line has also required more than 82,000m² of diaphragm walls with tie-rods. More than 68,000m of anchors and bars have been utilised together with 218,000m of tie rods (20 to 60 tons).
Main quantities:
Excavation works volume 3,400,000 m3
Embankment 11,060,000 m3
Concrete works volume 160,000 m3
Underground excavation works 2,445,000 m3
Tunnel concrete lining works 483,000 m3

That's a very one-sided view. Japan and Switzerland being both rather liberal (nowadays so-called "neoliberal") countries in an international comparison have by far the highest amount of railway passenger-km per head of population and public transportation is a crucial part of the lifestyle in these countries.

In the case of Switzerland, the biggest part of the railway network was built by private entrepreneurs in the most liberal decades of the country's history.


@railfan: Great summary and infos!!

Is there actually a thread where one can see an overview map of the most important railway lines in South America?

In well developed, prosperous nations, the private sector has the wherewithal and the government has the regulatory mechanisms in place to ensure a good quality product is produced.

In a developing nation like Venezuela, any private sector involvement would be ebset with corruption and backdoor sweetheart deals.

At the time when the biggest part of the railway network was built, Switzerland was not a developed, prosperous nation. It became one exactly during this time. It was around 130-140 years ago, so Switzerland was for sure economically much less developped than Venezuela is today.

Corruption and backdoor sweetheart deals are an inevitable phenomenon in societies with a lot of power concentration in the hands of a few, no matter if this power concentration is officially part of the state or private sector. Anyway, if there is a lot of power concentration, it mostly includes influence on both the state power and the biggest enterprises at the same time. State and private sector need to be clearly divided, in order to create a balance of power.

I am not saying that I know what is best for Venezuela. But to state that private sector involvement is always bad for railway development is for sure wrong which is shown by many examples.

It seems to me rather that in the development stage, private sector involvement might be better, whereas in situations where there exists a quite dense network already, it becomes more important to coordinate the network by the state or a private association in order to get the best out of it.

Anyway, for every country there is a different suitable path.
