TALGO (Tren Articulado Ligero Goicoech
ea Oriol, Goicoechea-Oriol light
articulated train), Alejandro
Goicoechea and José Luis Oriol being the
founders of the company.
Talgo Patents S.A. was first incorporated
In March 2007 Talgo sold its Finnish
rolling stock manufacturing subsidiary
Talgo Oy to its local management and
other Finnish investors. The company,
which Talgo had owned for only seven
years, reverted to its previous name
of Transtech Oy. The company spends 10
to 12 percent of revenues on research
and development, but the main
revenue source is the Spanish railway
Talgo made an initial public offering on
the Bolsa de Madrid in May 2015. The
IPO valued the company at €1.27
In July 2015, Talgo stated its intention to
ship a Series 9 train to India at its own
cost as a demonstration on the Mumbai-
Delhi rail route.
Talgo trains are best known for their
railway passenger car that uses a type
similar to the Jacobs bogie that Talgo
patented in 1941, similar to the Robert
Stephenson and Company trains.. The
wheels are mounted in pairs but not
joined by an axleand the bogies are
shared between coaches rather than
underneath individual coaches. This
allows a railway car to take a turn at
higher speed with less swaying. As the
coaches are not mounted directly onto
wheel bogies, the coaches are more
easily insulated from track noise. Talgo
trains fitted with variable gauge
axles can change rail gauge - for
instance at the 1,668 mm Iberian
gauge/1,435 mmstandard gauge at the
Spanish-French border interchange.
Since the introduction of the
Talgo Pendular in 1980, the train tilts
naturally inwards on curves, allowing it
to run faster on curves without causing
discomfort to passengers. The carriage
tilting system pivots around the top of
the suspension columns, which has the
effect of partially cancelling out the
effects of the lateral acceleration when
Here's all you need to know about the
Talgo trains that we are about to welcome
on our railway tracks:
1. A Talgo 250 can run at the speed of 250 kmph.
However, trials in India will only be conducted at 150-
2. Its lighter trains can cut travel time by 30
per cent. In fact, Talgo trains are expected to
cover the Mumbai-Delhi stretch by 12 hours,
unlike the Rajdhani which takes 17 hours.
3. Talgo train coaches would save up to Rs 1
crore as compared to the LHB coaches used
in Rajdhani and Shatabdi trains. They are
also said to require "less maintainance".
4. Unlike that for Japanese bullet trains, no
major overhauling of tracks is said to be
required for running Talgo trains in India.
5. Amenities like footrests, reading lights,
tables, audio entertainment control, etc. are
provided for every individual seat. The trains
also come with monitors for video entertainment.
6. Talgo trains have the technology to keep
interiors pleasant even when the temperature
outside crosses 50 degree Celsius or drops
below -20 degree Celsius.
7. Talgo's official website also promises showe
units, in-house restaurant and a cafeteria car
for pasenger coaches.
8. Talgo trains' can also reduce Railways'
energy bill by 30 per cent, as its "reduced weight
and inalterability against atmospheric agents is
translated into lower energy consumption"
9. Talgo 250 was the first high speed train to
run in Central Asia. In Uzbekistan, it runs on a
10. Pretty and efficient, yes, but these fancy
Talgo trains will make train travel more
expensive than it is now.
The progress of the Spanish rail
company Talgo conducting trial runs of
its trains in existing Indian tracks :
The trials recently conducted on
Delhi Mathura stretch have
reported to touch a maximum
speed of 180 kmph.
From 1 August trials are planned
to be done on Delhi-Kota-
Vadodara-Mumbai track and the
distance is planned to be covered
in almost 12 hours.
Talgo coaches are comparatively
low in height as that of
conventional coaches,thus are
more stable at higher speeds and
are having tilt mechanism to have
great speed even on the
curves,which predominantly exist
in IR tracks.
The Spanish-made high speed trains,
Talgo, will soon be pressed into service
but only after modifications to set them
operational for Indian platforms,
UPDATED ON 2–8–2016 16:00 HRS
Talgo’s nine-coach train, pulled by an
Indian Railways engine, departed from
New Delhi at 19:55 hours on Monday.
Talgo’s train, owing to heavy rains enroute
and point failure at Mathura Junction,
reached at 11:36 AM at Mumbai Central.
Rajdhani Express takes 15 hours and 50
minutes to traverse the distance between
New Delhi and Mumbai Central. If Talgo’s
trial had gone as per schedule and without
any glitches, the train would have taken 12
hours 47 minutes for the journey, that is
approximately 3 hours less than Rajdhani.
Railways to start trial of Talgo trains on
Delhi-Mumbai section from August One
NEW DELHI: Indian Railways will start the
trials of Spanish-made Talgo trains on the
busiest Delhi-Mumbai section from August 1
after its successful trials on Mathura-Palwal,
where it achieved 180 kmph with fully loaded
The trials on Delhi-Mumbai section will be
done at a maximum speed of 150 kmph for
nearly a month before a report is submitted
to Railway Board. At present Delhi-Mumbai
Rajdhani runs at an average speed of 80
kmph covering 1388 km distance between
the two cities in 16 hours. Talgo coaches
can cut the journey time between Delhi and
Mumbai by 4 hours 30 minutes.
“The primary results so far are similar to as
claimed by the company and we will make a
detailed report on other technicalities. Next
week we will conduct trials of emergency
braking distance system which means
distance it takes to stop after applying
emergency break at 160 kmph,” said a
senior railway officer monitoring the trials.
With Railways working to increase speed of
trains, Talgo trains can be a game changer if
they succeed in achieving claimed targets of
running on existing rails at 180 kmph without
any major infrastructure changes. At present,
Gatimaan Express is the fastest train at 160
The cost of a Talgo coach is Rs 5 crore and
it requires minimal infrastructure upgrade to
run on Indian rails. Talgo envisages the
journey between Delhi and Mumbai can be
completed in about 11 hour 40 minutes as
compared to 16 hours 10 minutes at present.
The Talgo coaches can run on curved rails
without decelerating speed. Besides
reducing travel time, Talgo's lighter trains
consume 30 percent less energy. The
Railways has set up a Mobility Directorate to
work on strategies to increase speed of
trains. Gatimaan Express – India's first
semi-high speed that clocks 160 kmph, was
launched on the Delhi-Agra route in April.

•TALGO's RD System, used to change automatically
the distance between the wheels of the axles, has
been successfully used since 1968 in variable-gauge
axles of Talgo's trains.
•The TALGO RD System permits the automatic
change of the distance between the wheels of the
railway vehicles in order to make possible the running
on different gauge tracks.
• The TALGO RD system can be applied to different models of passenger coaches, power heads, locomotives and
freight wagons with full security and reliability, through standard /Spanish and Russian / standard gauge Railway
• The change is made without human intervention while the train is running at low speed (15 Km/h) through a special
installation fixed on the track in betweenthe tracks of different gauges.
• This is a unique and simple system based on the elevation of the suspension above
the Centre of Gravity of the carbodies. This system is used to reduce the lateral
forces that affect passengerswhen traveling on curves.
• The carbodies act under the effect of natural ( centrifugal ) forces without any loss of
safety and comfort levels, thanks to the steered wheels and the unique talgo
wheelset assembly characteristics...
