The "eccentric" thing to my mind is having a door with a handle on only one side. We all know why that was done (though do all passengers know that?) but it's a bit of a neither here nor there solution, compared to either modern-conventional push buttons or a door with handles on both sides, with an interlock to prevent opening in motion if deemed necessary (which it surely would be).
Perhaps 'eccentric' is an understatement. I presume that the inner handles were removed as a quick cheap solution, and the more expensive central locking systems came later:
In the 1980s, fatalities due to falls from moving trains were on average 20 per year and were a growing public concern. In 1991/92
HMRI▸ were part of an
HSE▸ investigation which looked into the cause of these incidents including examinations of the design, operation and use of train doors and locks and the associated installation and maintenance procedures used by British Rail.
The subsequent published report (passenger falls from train doors, report of an HSE investigation) found that there was evidence of poor maintenance procedures, doors and locks poorly fitted and a design failure. The report, published in 1993 and its recommendations implemented by the industry, resulted in a significant decrease in fatalities and serious injuries.

http://www.railwaysarchive.co.uk/docsummary.php?docID=393It concluded that
BR▸ really ought to maintain their locks properly, but falls short of insisting on removing inner handles or installing central locking systems. Many accidents seem to have been ascribed to misalignment; in the worst cases a door would jam in its frame with the lock stuck open. In some cases it is believed that in attempting to close doors which had half-caught, passengers tried to open them to get a better slam, and were hauled out of the speeding train as the door swung open. Horrifying.
