It was great to see the return of BBC’s Sherlock with series three’s opening episode The Empty Hearse (spoiler alert). Others have already commented that there were inconsistencies in scenes that took place in the Tube (London Underground), some of which are particularly obvious because of the division of the Tube network into sub-surface lines and deep-level lines with different rolling stock used on each line. A few of the more obvious things I noticed:
Not the District line
The supposed security footage of a train running on the District line between Westminster and St James’s Park actually shows a deep-level tube station and train, either a 1996 Stock (Jubilee line) or 1995 Stock (Northern line). In real life, St James’s Park station is only served by sub-surface lines (District line and Circle line) running D Stock and S Stock trains.
Bigger on the inside
When Sherlock and Watson find the missing train car sitting in a disused tunnel, it’s now mysteriously transformed into a 1967 Stock train (formerly used on the Victoria line). When they enter the train, however, our protagonists find themselves inside a sub-surface D Stock train (District line). It’s bigger on the inside! (Is it a coincidence that co-creators Steven Moffat and Mark Gatiss also work on Doctor Who?) But at last the train shown is consistent with the plot.
I’m sure there were good logistical reasons for all the swaps – it’s likely that the producers used whatever footage and sets were available rather than incurring the expense of building new ones just for consistency.
