I take the B to work most mornings from CPW to 47-50. Ordinarily R40s exclusively run on the B (so far as I can see anyway), but recently I've seen trains of R68s (which usually run on the D). In the 8 months I've been taking the B to work this is the first time I've seen this-- does anyone know if there is any particular reason why?
