0-60 time of a 185

[MCR247]

Was it? Didn't know that

 

[colchesterken]

the 170s we had on the GEML seemed to pick up speed well
when you look at the power they have compared to 1 st generation DMU s the
115 s we had on the Aylesbury line had 4x 150 hp per 4 car set they took forever to get up to 70

 

[MCR247]

The acceleration on 170s is shocking!

they have 420hp Mercedes 6R183 TD13H in-line 6 engines so they're bound to be pretty mippy for a DMU. The 185 should still beat it for acceleration though, quite easily.

170s are not fast accelerating DMUs! A 156 would outrun it and 158s do

No DMU would set the world alight on acceleration EMU's, where the maximum torque is available instantly, are a different kettle of fish altogether

Put a 185 next to a 323 out of Piccadilly then. There is hardly an difference!

I realise this, but what I was saying was that acceleration is not one of the strong points on 170s

Yeah, but I wouldn't call leaving Piccadilly a timed, full on throttle race, would you? lol The 323 would easily beat the 185 from standstill to 60

A well running 180 has no problem catching up and passing a 221.

From what I remember a 180 should hit 125mph in around 3 minutes. A 185 hits 60 in just over a minute (conditions depending).

It would beat it to 20/30, but from above 40 the 323 tails off. A 185 would rip it to 60. Anyone here want to arrange a race?!

A 220/1/2 will beat a 180 to 125. Above a 100, the 180 crawls up to 125 while the Voyager family keep going steadily. I was always under the impression a Voyager will outstrip a 180 to 100 anyway, they're quicker from a standing start and put the power down better, despite being heavier.

The 3 minutes quote comes from the training video I was shown a few years ago. From experience up to about 80mph the 180 has the edge over the 221, I've left alongside 221s or just behind them and managed to pass them on numerous occasions. Once over 80mph the 180 loses it's edge over them but the needle still climbs fairly quickly.

Mmmmmm, thinking about it, you could be right there but I'm not too sure. The 185 would have it on 'in-gear' times I suppose (50 -70, 30 - 70 etc etc). I wish we could put it to the test and have a drag race.

I would like to bet the 180 would start to smoke and slows down before it reaches a ton!

Coming out of Edge Hill, they can achieve a speed increase of 45mph in just under 30 seconds (I think the line speed through Mossley Hill is 85, Driver9000 will confirm/change as applicable).

Mossley Hill platforms are UF 70, DF 80, US 75 and DS 30. Up is heading away from Liverpool.

Why would the slow line have a faster speed limit than the fast line?

Most likely curvature of the line or signal sighting. It's one of the quirks of the approaches to Lime Street too in that the Fasts are a lower line speed (30) to the Slows (40).

Not too familiar with that stretch of line but the approaches to LS are quite bendy in that vicinity so you're probably correct as usual.

Ta for that. So in actual fact 40mph in under 30 secs. Impressive!

Not entirely correct.... Its down to maintenance. I drive 170s, also did 158s and 156s in Central days... In the past couple of years XCs 170s have had a slight performance improvement as the power was not set at full to reduce maintenance costs. We often race a 158 out of Ely to Ely North and they are equal more or less. From a punters view 170s feel slower inside...
