Co-incidence of rolling stock and timetable numbers.

From https://en.wikipedia.org/wiki/British_Rail_Class_115

Coincidentally, Class 115 units operated services under Table 115 in the British Rail timetable.

Are there, or were there any other unit / locomotive class types operating on tables of the same number?   Westerns on Bedford to Brighton anyone?

Not a rolling stock class type per se, but services on Table 125 (London - Swindon, Cheltenham Spa, Bristol, Weston-super-Mare and South Wales) were, until the arrival of Class 80x, mostly operated by HSTs^▸ (High Speed Train), aka InterCity 125s.

Class 117s were used on Table 117 routes (Paddington to Reading), and Class 121 'Bubble Cars' would no doubt have worked trains on Table 121 (Slough to Windsor).

Interesting question.

SWR^» (South Western Railway - about) Salisbury- Romsey are shown as part of the Waterloo to Bournemouth service, which is table 158...

Looking back to an old timetable ... I was amused at the idea of a deltic hauling a train from Kettering to Corby, a compton on the front of a Sheffield to York local, or a class 37 at Ilkley.  I can imaging a Brush 47 between Newcastle and Berwick upon Tweed, and a tadpole on London to Hastings via Tunbridge Wells was a near miss (wouldn't have been such a near miss with the wide carriage against the sides of the tunnel!)

That's NOTHING...

I have a much more nerdy co-incidence in railway-related matters.

Train descriptions, of the form "number letter number number" can be valid hexadecimal (base 16), if the letter is A-F.
In the ARS^▸ (Automatic Route Setting) system memory, times are stored in "number of 5-second units since midnight", as this can be stored in a 16-bit "word", which is also represented in hex as 4 characters.

If ARS is waiting for a train's departure time, then that gets output, in hex, on the ARS system log.
I'm still waiting to find a train waiting for "itself".  1A04 leaving somewhere at 0915 would fulfill the criteria - because 1A04 (hex) is 6660 (decimal), or 33300 seconds since midnight.

Not all hex numbers become valid departure times, since only on-the-minute or on-the-half-minute are allowed departure times.  Conversely, not all valid departure times can be train descriptions, because the 1st, 3rd and 4th characters must be numeric, not A-F.

Think I need to digest that one, ROWER40, over a gin and tonic or two.....
