I think it’ll have been 24s you’ve seen photo’s of - Inverness type 2s worked the branch and that depot seemed to use their 24s and 26s indiscriminately.It's a 26 details from the link below the pic:
"Birmingham RCW Type 2 (Class 26) No. D5335 heads the branch train, consisting of a single ex-LNER non-corridor brake composite carriage, at Aberfeldy on 1st May, 1965, the final day of services on the branch."
I first came across the Aberfeldy branch a few years, I think from a thread on RMweb. For it's final 2 years of operation all services were diesel operated, either single coach passenger services like this or mixed trains with a few wagons/vans added, I've seen pictures of 25s on the same line.
Most of them were. But three were used as test beds for the 87 orders (like 47 046, became 601 and then 901). They had 5,000hp.Agree with the 87s, but seem to recall the 86s were quite a bit less powerful??

Don't forget the 153 won't have 350hp at rail either due to transmission losses and other loads such as compressor, alternator. The 26s are quoted as 900hp at rail (admittedly not over the entire speed range) so think 26 + 1 mark 1 would win there.26 isn't it?
1160hp at the flywheel, maybe 850hp absolute maximum hp at rail, 75 tons of loco and 30 tonnes of MK1 makes it slightly less hp for the coach than a solo 153?
Oh yes, was thinking of 158s; they're even worse with only 285hp.153s are 285hp too, probably 200hp at rail at best
Not as good as the 2 x Taurus on four coaches I mentioned earlier!In The Netherlands, we have our Intercity Direct trains, which are 7 coaches (6 in the past) with top-and-tail Bombardier Traxx locomotives at 5.6 MW or 7,500 hp per loco, so a total of 11.2 MW or 15,000hp over 550t total weight. Does that count?
I was going to mention that combo, but saw you'd beat me to it! I saw such a train at Villach, featuring a 1016 and a 1116, both with pans up and just 4 coaches.Not as good as the 2 x Taurus on four coaches I mentioned earlier!
Mind you, the most "throw you into the seat" performance I've ever experienced was a pair of SBB Re460s on 11 coaches leaving Chur 12mins late (waiting bus connection of course!). Think it must have been a Zürich driver on his way home - the acceleration was something else and he was clearly using every kW of power available. Braking for Landquart was equally impressive, hitting the platform ramp at around 70mph and stopping perfectly in the right place. Sadly had to leave the train there, but watching the departure from Landquart - by now just 8 late - it wasn't going to be late by Zürich!I was going to mention that combo, but saw you'd beat me to it!

You measure the pulling power of a locomotive by looking at its tractive effort (kN) more than its power (kW), ...
Since this thread is full of pedantry already, I suppose I might as well mention that what "throwMind you, the most "throw you into the seat" performance I've ever experienced was a pair of SBB Re460s on 11 coaches leaving Chur 12mins late (waiting bus connection of course!).
