The short answer is no !
If you go past in the train you see a lot of roofs as the main line is slightly higher than the sidings. You can see at least the two in the siding next to the main line from the adjacent road, but the undergrowth is bad at this time of year and depending upon how they are parked you can get perhaps two or three numbers from the acess gate near the Wreccelsham end of the adjacent road (past the school). You can also see the front ends of some units from Wrecclesham road which runs past the end of the depot, but again there is difficulty with differences in height, trees, undergrowth and seeing through two horrible fences.
With perseverance and binoculars you can get some numbers, but certainly not all - particularly those at the London end of the formations can not be seen, with the odd exception, all depanding upon exactly how they are parked.
