TERMS OF REFERENCE (TOR)

FOR

Consultancy Services for Feasibility Study and Detailed Design of New Rail Link

From Lashkargah to Bahramcha (260 km approx.)

TOR FOR LASHKARGAH-BAHRAMCHA


1. BACKGROUND AND OBJECTIVES

The railway line Lashkargah – Bahramcha which connects Afghanistan to Gwadar port (Pakistan) is vital for

the development of the significant regional and international transport corridors e.g.

Transport Corridor Europe-Caucasus-Asia (TRACEKA), Central Asia Regional Economic cooperation

(CAREC), Lapis Lazuli etc. which are in progress.

The Lashkargah - Bahramcha railway project is a part of Afghanistan Railway corridor- 2 (Herat–Farah–

Helmand–Kandahar–Zabul, Ghazni–Logar and Kabul). It is one of the most important railway links, as it

connects Afghanistan with neighboring country Pakistan and to South and Central Asia through Gwadar port.

Gwadar Port is situated on the shores of the Arabian Sea in the city of Gwadar, located in the Pakistani state of

Baluchistan. The port is located 533 km from Pakistan's largest city, Karachi, and is approximately 120 km

from the Iranian border. It is located 380 km (240 mi) away from Oman, and near key oil shipping lanes from

the Persian Gulf. The greater surrounding region is home to around two-thirds of the world's proven oil

reserves. It is also the nearest warm-water sea-port to Afghanistan.

1.1 Project Objectives

Linking Afghanistan railway to Gwadar port

Regional connectivity

Improve railway connectivity to Pakistan, South-Asia and Central-Asia

Development of Railway transport infrastructure in Afghanistan

Employment and job creation

Contribute to the regional development in terms of economic transit and commercial goods.

Social and environmental safeguard development

It is to provide a large-capacity transport channel, which would play a positive role in

enhancing the economic and social development in Afghanistan. It can promote the development of mineral resources along the line, so that the resources superiority can be changed into the economic advantages. It can promote the building of north-south transportation main artery of Afghanistan to strengthen the exchange of goods between Afghanistan and the world

1.2 The Afghanistan Railway Authority (ARA) was established in November 2012 within the Ministry of

Public Works (MoPW) following the decision of the Afghan Government’s Cabinet. Now it is an independent

government authority and is the governing body for all railway sector planning, implementation of the

National Railway Plan, development of network, operations and maintenance (O&M) of the railways in the

country. More importantly, ARA is responsible for the legal and regulatory policies governing rail investment,

development, and operations.

Afghanistan Railway Authority, on behalf of the Government of Afghanistan, aims to recruit a firm for

Feasibility Study and Detailed Design of New Rail Link from Lashkargah to Bahramcha (260 km approx.) in

accordance with the Procurement Law and Procedure of the Government of Islamic Republic of Afghanistan.
