Introduction
Through long term experience in the fields of intercity and urban railways’ track design
and construction, we have virtually conquered all local track-related projects in Iran. From track
laying in ballasted intercity railways in Iran (more than 2000 km.) we have extended our services in
railway track engineering consulting and EPC projects. We have our footprints in Tehran, Mashhad
and Isfahan Urban Railways.
Our key personnel include best governmental supreme managers to well-educated
professional private engineers whom all have devoted themselves to development and
improvement of railway track engineering construction and engineering services.
We follow the best procedures world-wide and are keen in newly developed technologies
in railway track and signaling systems. Also due to very good binding with domestic track
elements’ manufacturers our prices are very competitive.

1- Main Expertise
2-2- Railways (Intercity Railway)
The proper choice of a track system depends on many factors. Each project, after all,
places different challenges. Which system is the best for a certain application? Is a ballasted or a
non-ballasted solution advisable? Sometimes a simple solution will lead faster to your goal – and
sometimes a sophisticated system is the better solution over the long run. In any case, T.O.J. Co.
can offer the appropriate solution: We help you to find the right way.
A track system by T.O.J. Co. is always a tailored solution, in which systems are adapted to
special requirements. Curves, bridges, fill sections, tunnels, and turnouts place the strictest of
requirements on the route. Foundation-soil characteristics have crucial consequences for planning.
What physical forces and environmental influences can be expected? How will the soil react to
operational loads over the long run? And: What logistics requirements must be considered during
construction? After all: optimization of the process chain is our primary goal, and this includes
construction-site access, transport paths, and material supply.
2-3- Urban Traffic
Innovative concepts in urban traffic make our cities more worthwhile to live in. But
nowadays, foresight is more important here than ever: the coexistence of people, means of
transport, and other machines in crowded spaces demands intelligent and ecologically harmonious
solutions – not only in planning and logistics, but likewise during construction phases and during
transport operation. T.O.J. Co. offers innovative system solutions for all requirements of mass
rapid transit. And since each track system should be optimized for its special area of application,
T.O.J. Co. places special emphasis on close collaboration with our customers and business
partners.
Any public transport project in urban zones is just as individual as the city in which it is
implemented. Continuously new requirements challenge engineers and planners: urban
architecture, bridges, overpasses and tunnels, impressive squares, train stations, and malls and
shopping centers exert critical influence on the selection of systems. How do structures near a rail
line react over the long term to rail operating loads, and how should we protect them? In downtown
and residential areas, the public increasingly voices greater expectations for aesthetic criteria.
2-4- Heavy-Haul Railways
Due to heavy axle loads and special operating conditions these railways require special
attention in track design. Although the applied track system in most of these railways is ballasted
track but special attention should be given to track elements such as rail grade and dimension,
sleeper type and spacing and high-duty fastening systems.
T.O.J. Co. has long experience in freight and mixed railways lines across Iran and is
willing to submit all valuable experience to its oversea client. Main track design criteria for us in
this field are availability, punctuality and safety.

2-5- Track Engineering Services
As an EPC contractor we have equipped ourselves with best track engineers and now we
are engaged in all track related project in all phases including feasibility studies, preliminary
design, basic design and detail design. Also our services are extended to track construction
management and supervision.
Our engineers have a long-term experience in Tehran, Mashhad, Shiraz, Isfahan and Ahvaz
urban railways and currently are supervising the track construction in Shiraz and Isfahan.
Following pictures shows are sample sheets which were presented to our Clients for previous track
design projects.
