Crash Engineering Solutions Limited has carried out numerous Feasibility Study Cases. Presented below are selected samples.

CASE STUDY 1: Feasibility Study -  Vietnam Railways, 2009 VIETNAM

Vietnam, a Costal Country on the Indochina Peninsula in the South East Asia considered the construction of a single track of standard-gauge high speed rail link running from Hanoi in the North to Ho Chi Minh City is the South. The track was to cover over 1720 km. 

The Problem:

  • the line was more than 130 years old and dilapidated in many parts;
  • bridges along the track were weak to carry the dynamic loads from modern fast trains;
  • train speed restrictions of 50km/hour and in many parts dropping to 20km/hour hindered track efficiency and was dangerous in terms of safety;

The Solution:
As part of a team of companies we were contracted:

  • to carry out a pre-feasibility study to analyse the safety aspect of the current line and draw new requirements for the future line;
  • to pre-design the type of rolling stock that will be suggested for use by the operator based on the proposed line characteristics so that speeds of up to 100km/hour could be attained;
  • Design rolling stock including crashworthiness capability by employing safety features, namely lifeguards for derailment prevention, buffers and anti-climbers for frontal crash management and for preventing overrides. All numerically tested to EN 15227:2008+A1:2010 Crashworthiness Requirements For Railway Vehicle Bodies.  

CASE STUDY 2: Feasibility Study - The Elizabeth Line Crossrail, 2010 UNITED KINGDOM

The Elizabeth line is a new railway line for London that will run for nearly 100 km (62 miles) from Abbey Wood and Shenfield in the East to Heathrow and Reading in the West. This is a Crossrail Ltd project budgeted at GPB17 Billion. 

The Problem:

  • The current partial line is made up of old infrastructure;
  • plan is to tunnel 21 km of underground that will accommodate the new tracks with a lot of bends.

The Solution:
As part of a team of companies we were sub-contracted:

  • to carry out a feasibility study of the tunnel dynamics and load attenuation characteristics in railroad design. Due to numerous bends it was necessary to analyse the modes of the train oscillations and how these amplitudes affect the rail track wearing behaviour;
  • to carry out analysis of the temperature distribution along the railroad under variable natural conditions in the tunnel;

CASE STUDY 3: Feasibility Study and Project Management - Zambia Railways, 2012 ZAMBIA

Zambia, a country in Central Africa considered the rehabilitation of the exisitng single track that stretches for over 1100 km from Livingstone Town in the South to Chililabombwe in the Copperbelt province in the North.

The Problem:

  • the line was more than 100 years old and dilapidated in many parts, resulting in numerous train derailments per year;
  • bridges along the track were weak to carry the dynamic loads from modern fast trains;
  • train speed restrictions of 20km/hour and in many parts dropping to 10km/hour hindered track efficiency and dangerous;
  • locomotives and the entire rolling stock were not-fit-for-purpose and needed replacement.

The Solution:

We were requested to provide a solution:

  • to carry out a feasibility study on the rehabilitation of the existing dilapidated railroad;
  • to carry out the analysis and design of the new second railroad to carry northern bound trains;
  • to carry out an analysis on the electrification of both lines since the country did not have its own source of hydrocarbon fuel;
  • To propose the locomotives and entire rolling stock for the future railway;
  • To carry out an economic analysis of how business by Zambia Railways Ltd could be spread to other income sources;
  • To analyse the possibility of proposing a modular construction system that had each section covering over 100 km.

CASE STUDY 4: Feasibility Study - Tramways in the Cities of Lusaka and Kitwe, 2015 ZAMBIA

Zambia considered to contribute to the reduction of its carbon foot print through the realignment of the transport system. The country was awarded the UNDP NAMA funding to carry out a feasibility study for alternative transport framework that reduced the GHG emissions. The funding was supported by The European Union, The German Government, The Australian Government and The Rebulic of Zambia Government. 

The Problem:

  • The mix of transport system in the country is predominantly vehicles that use hydrocarbon fuels. A need to reduce Zambia carbon footprint was proposed;
  • The country experiences unprecedented traffic jams with high economic losses;
  • Public transport is inadequate and needs either rehabilitation or new thinking all together if the rapid growth in population will have an efficient and effective city transport network. 

The Solution:

  • We were contracted:
  • to carry out a pre-feasibility study to find the National Appropriate Mitigation Action (NAMA);
  • to carry out an Environmental Impact Assessment;
  • to carry out a design of the tramway in Lusaka and Kitwe;
  • to carry out the selection of trams to meet future demands.


CASE STUDY 5: African Development Bank (AfDB): Rail Network for Africa, 2015 IVORY COAST

The African Development Bank (AfDB) organised a Transport Forum where world specialists in railway infrastructure and rolling stock design were given a chance to propose the African solution. Crash Engineering Solutions Limited of UK was invited to deliver a Keynote:
