OSShD is the Latin transcription of the Russian abbreviation ОСЖД (Организация Сотрудничества Железных Дорог  - Organisation for the Combined Operations of Railways). The Chinese characters 铁组 are pronounced tiě zǔ - Iron[way] Group.
(Note that as the transliteration from Cyrillic to Latin letters is different among various languages, you may also come across the spellings OSJD or OSZhD.)

The OSShD is headquartered in Warsaw and was founded in 1956, its membership is comprised of the Transport Ministries and central state bodies responsible for railways. The main areas of OSShD's activity are the development and improvement of international rail transport, particularly between Europe and Asia, including combined transport, coordination of international rail traffic transport policy; improvement of how standard (1435 mm) and Russian wide gauge (1520 mm) rail networks work together; co-operation with other international organisations; improvement of international transport law.

It currently has 25 member states (Azerbaijan, Belarus, Bulgaria, China, Czech Republic, Estonia, Georgia, Hungary, Iran, Kazakhstan, Korea (North), Kyrgyzstan, Latvia, Lithuania, Moldova, Mongolia, Poland, Romania, Russian Federation, Slovakia, Tajikistan, Turkmenistan, Ukraine, Uzbekistan, Vietnam) plus four observers (Finland, France, Germany, Greece). The trackage of the members combined equals nearly 300.000 km or roughly a third of the world's railways trackage. In the former COMECON and some neighbouring nations, OSShD was the common railway standardization body and remains so today.

Among other things, one important subject they were able to standardize are the colour light signals, which have very similar aspects throughout the member states, so you can drive your train from East Germany to Vietnam while seeing just about the same signal aspects.

Upon the Reunification of Germany, the member state East Germany ceased to exist while Germany took observer status.
