OK, here goes....
In his book, Obachike implies that his usual route to work that week involved walking from his home to Enfield Town railway station, catching the 08:27 train to Liverpool Street station, then changing to the London Underground to complete the journey to his office at Old Street. Logically this would mean taking a Circle/Metropolitan/Hammersmith & City line train to Moorgate station, then changing to the northbound Northern line to go one stop to Old Street station. Obachike says that this would get him to his desk before, "the petulant manager came a-hovering minutes after 9" (p. 5).
On 7 July, however, he missed the 08:27 train, and so had to get the next one, but en route he changed to the Victoria line at Seven Sisters station (six stops after Enfield Town, and eight before Liverpool Street) for no adequately explained reason. The logical alternative route would have been him taking the Victoria line all the way to King's Cross station, before changing to the southbound Northern Line two stops to Old Street station. He says, "a glance at his watch told him it was almost 9 o'clock" (p. 10) as they approached King's Cross/St Pancras, but it was announced that the station was closed, so the train passed through without stopping. Once at Euston, he states that the train doors remained open for "minutes," then "another 5 minutes later passenger's frustrations began to tell," before most progressively began to leave, himself included, their exit slowed due to the power to the escalators to the mainline surface station being off. From personal familiarity with the station layout at Euston, it is hard to accept that someone could reached the surface in less than ten minutes under these circumstances. At the very least, then, it would have at least 18 minutes between the arrival of the train and Obachike reaching the surface, which he claims he actually did by
09:06. He then spent a further 25 minutes milling around with other displaced communters, before eventually boarding the No. 30 bus and departing at
09:31.
There are a number of problems with both his claimed usual route, and the one he says he actually took on the day. In the first instance, in July 2005 the 08:27 from Enfield Town was not timetabled to arrive at Liverpool Street until 09:04, so with another ten minutes to get to Old Street by Underground, it's hard to see how Obachike could have been at his desk by 09:20, let alone "minutes after 9."
As he actually missed the 08:27, the next train was not until 08:49, arriving at Liverpool Street at 09:26. It would have arrived at Seven Sisters 1-to-3 minutes before it was timetabled to leave there at 09:03, but then taken him around four minutes to change to the Underground, and another 10 minutes to get from there to King's Cross, so he could not have been approaching that station at "almost 9 o'clock." Even with trains non-stopping at King's Cross, he could not have reached Euston until around 09:16-09:18, assuming that he got straight onto an immediately departing Victoria line train at Seven Sisters, meaning he could not have been on the Euston mainline concourse until 09:34-09:36, after the No. 30 had departed, never mind allowing his 25 minutes elapsing before that happened.
This all assumes that Obachike took the route he says he did. As noted, he claims he walked from his home to Enfield Town station, which is a distance of about 460 metres, to take a 37 minute train to Liverpool Street, followed by a further Underground journey with an additional change to Old Street. In the oppose direction, 880 metres away from Obachike's home, is Enfield Chase station, from which he could take a 24 minute train on a different line
direct to Old Street. In July 2005 the timetabled departures and arrivals at Enfield Chase and Old Street were respectively:
08:17 - 08:45
08:27 - 08:52
08:34 - 08:58
08:39 - 09:04
08:58 - 09:24
09:02 - 09:28
The only Enfield Town to Liverpool Street services in the same timeframe were:
08:12 - 08:47
08:27 - 09:04
08:49 - 09:26
09:04 - 09:38
All the issues of whether Obachike's described route could actually get him to Euston in time to be on the No. 30 bus aside, it does not seem credible that that for the sake of not walking an additional 420 metres, he would make a more complex journey (i.e. three changes rather than
none) that would take
at least 22 minutes longer every single day, let alone one on which he was already running late. Ironically, elsewhere in his book Obachike actually makes the point that savvy commuters, "naturally opt for (the) quickest and most straightforward journey" (p.123).
