The Babylon Stations
Babylon 1, originally known simply as The Babylon Station, was the first space station built by the Earth Alliance under the Babylon Project.  During construction, Babylon 1's infrastructure collapsed and exploded as a result of sabotage. Construction worker Thomas Jordan had just left the station.  Part of its materials were recycled to construct Babylon 2.
The second attempted station in the Babylon Project, Babylon 2 was also sabotaged and destroyed, exploding during construction. Part of its materials were also recycled to build the next station. It is believed to have been coloured orange and was slightly smaller in scale.
Babylon 3 was sabotaged and destroyed, exploding during construction. After it was destroyed, leftover materials were used in the construction of Babylon 4, which were present, even when Babylon 4 came online in 2254.
Babylon 4 disappeared 24 hours after it became operational.
Babylon 5 was ultimately constructed and was the final Babylon station.
- Though only Babylons 1, 4 & 5 were ever seen, it appears as though they were colour coded in spectrum order (Red, Orange, Yellow, Green & Blue), which would make the unseen Babylons 2 & 3 Orange and Yellow respectively.
- JMS has stated that the intended design of the first three Babylon stations was the same as that of B4, though none of them got anywhere near completion. However, what little was seen of the (incomplete) Babylon Station in "In the Beginning" shows that it was a somewhat different design than either Babylons 4 or 5.
