The online collection presents those objects on permanent display. At the head of every section or theme, there is a brief introduction describing the theme, number and date range of objects. At the object level, there is also a brief description, dimensions, date, ID number, and related objects. Additional resources, such as links to essays and other online exhibits (for example, Exploring 20th Century London, which I will definitely explore later).
The Online Museum project was supported by funding from Renaissance London ("museums for changing lives") and developed by the Digital resources project team (the individuals are listed). No collection policy or digital practices were discussed.
The museum definitely has a tourist feel, but I believe there is research value in the information they are providing. It could certainly provide an interesting starting point for research in transportation, graphic design, public transportation trends, etc.
