RMweb Gold Popular Post big jim Posted April 13, 2014 Author RMweb Gold Popular Post Share Posted April 13, 2014 a few more pics.... yesterday i did a bescot-mountsorrel-hinksey job which i picked back up this afternoon and took back to bescot one from the verhanda on the 70 while waiting for this to cross my pass after picking up the train i headed back towards hinksey via nuneaton, stopped in knighton loop to let a MML pass and into oxford after running round in hinksey and onto today, picked the loco back up at loughborough and worked it to bescot where it is stabled until i pick it back up again tomorrow and put onto 6V46 to westbury! couple of 60s stabled on the reception lines parked up couple of 97s 97302 97304 22 Link to comment Share on other sites More sharing options...

Really looking forward to a lemon yellow/orange 'tug'! Jack. Link to comment Share on other sites More sharing options...
Vin Posted April 14, 2014 Share Posted April 14, 2014 Hi Jim, Hope you get a go on the class 37's again? On the class 70's which end whines the most?? The fan/cooler group end or the alternator end? Regards Vin Link to comment Share on other sites More sharing options...
RMweb Gold big jim Posted April 14, 2014 Author RMweb Gold Share Posted April 14, 2014 The whole thing! Its the traction motors that whine, the dynamic brake end sounds good when you use it, its such a powerful brake its almost like driving a unit at times!! The scavenger fans make a good noise wheb they start up too, almost sounds like a chinook!! Just one pic from today, 70802 (again!) on 6v46 8 Link to comment Share on other sites More sharing options...
Vin Posted April 14, 2014 Share Posted April 14, 2014 Proper GE whine from every direction!!! Cheers Vin Link to comment Share on other sites More sharing options...
Vin Posted April 14, 2014 Share Posted April 14, 2014 Hi Jim, Does the dynamic brake put power back into the batteries? Vin Link to comment Share on other sites More sharing options...
RMweb Gold big jim Posted April 14, 2014 Author RMweb Gold Share Posted April 14, 2014 (edited) I think it puts the power back into the traction motors Edited April 14, 2014 by big jim Link to comment Share on other sites More sharing options...
RMweb Premium newbryford Posted April 14, 2014 RMweb Premium Share Posted April 14, 2014 Dynamic brakes use the traction motors as a generator and it dumps the power through a resistor bank. The resistors need to be cooled and it's the fans that howl. Quite a noise when descending the 1:120 or so behind my house with 1800Te on the back. (An electric loco/MU can have a regeneration brake where it puts power back into the OLE or 3rd rail). I think the same resistors are used to do a static load test on a 70 - it doesn't need a separate load bank. IIRC, Voyagers also have dynamic brakes and the resistor banks are on the roof, but they withstand a full load test. Dynamic brakes are also sometimes referred to as rheostatic brakes.

250BOB Posted April 15, 2014 Share Posted April 15, 2014 Jim, Have any Colas locos pulled any Charter Tours at all....??? My pal was wondering, as he needs haulage behind 4 of the 5 class 60's that were towed to Toton last week.??? Link to comment Share on other sites More sharing options...
Iron Horse Posted April 15, 2014 Share Posted April 15, 2014 I was only thinking the other day how popular Colas could be in the Charter market Link to comment Share on other sites More sharing options...
ess1uk Posted April 15, 2014 Share Posted April 15, 2014 coming into Didcot this morning from the A34 and there was a Colas 70 to my left just swinging round the bend towards Oxford so I couldnt see which one. it was around 0945 if anyone knows which loco was on the front. great pictures Jim Link to comment Share on other sites More sharing options...
RMweb Gold big jim Posted April 15, 2014 Author RMweb Gold Share Posted April 15, 2014 Probably 70802 on 6M50, im just waiting to pick it up at leamington, if they did a loco swap last night i'll let you know!! Link to comment Share on other sites More sharing options...
RMweb Gold big jim Posted April 15, 2014 Author RMweb Gold Share Posted April 15, 2014 Its 70803 on it, they did do a loco swap!! Link to comment Share on other sites More sharing options...

Cheers, Mick Its surprising just how much North American engineers (drivers) have to rely on dynamic brakes. Some of their grades are so many miles long and so severe that dynamics are an absolute must to get down the hill in one piece.. They will add many locomotives with dynamic brakes to descend a grade as they will to ascend it! Puts on a whole new perspective of train handling skill. With many of these long 10'000 ton plus freights, if you relied on just air alone you would probably become a runaway very quickly as you you'd either run out of air or burn out all the brake shoes! Wouldn't be the first time that's happened either. (Cajon Pass wreck 1989) Link to comment Share on other sites More sharing options...

(Cajon Pass wreck 1989) It's one of the main areas of tuition on simulators for some roads before they let drivers anywhere near real locos out on the road. the next most important area of training seems to be fuel economy.

Indeed Mike. There's a lot more skill involved going down than up! Slack run in (derailment risk) and then slack run out which can break the train in two. Both will get your back side fired out the door on many if not all of the class 1 roads in the U.S. They call it bad train handling. Anyway, ive derailed the thread topic slightly. Soz lads & lasses. 2 Link to comment Share on other sites More sharing options...
RMweb Gold big jim Posted April 15, 2014 Author RMweb Gold Share Posted April 15, 2014 some from today, a nice sunny day so lots of photographers about!! started in leamington where i picked up 6M50 to bescot, today we went via hatton instead of coventry park lane jn walsall, had to wait for this to cross my path, taken from the veranda again!! and into bescot where we picked up 70804 that i'd left there yesterday not the best shot coz of all the lineside equipment but just so you get an idea of how long the train is, 1500ft (409 metres) 97302 came down the goods to be dropped into the virtual quarry then a bit later 97303 came along to join it, so i got the full set as 304 was parked on the down side too!! thsi has been parked in bescot for a long time but i've only managed to photograph it for the first time today, the tank wagons were originally converted by my stepdads compamy (c.c.crump) in 1988 and the train was used for a short while before being laid up where it has just rusted away ever since!! couple more random shots... and on to saltney where i got off to wait for a taxi home so i got some more shots there the 70s head off to westbury 66568 passes the old saltney box and the new signalling centre xc 170 66591 day off tomorrow before heading down to hinksey in readyness to work a few engineers trains to southall via the chiltern mainline over the course of the weekend 14 Link to comment Share on other sites More sharing options...
RMweb Gold The Stationmaster Posted April 16, 2014 RMweb Gold Share Posted April 16, 2014 Typo alert Jim - Saltley has moved towards Chester And 1500ft of train - not even 75 SLUs so not very long by some standards (but then we used to run up to 120 SLUs occasionally and 100 was an everyday event so were well used to decent length trains). 1 Link to comment Share on other sites More sharing options...
