Sandites at Aylesbury

[dibber25]

The yellow one is a 122. The green 3-car was a 117 but has engines on what was a trailer car. The maroon one was 55024. The NSE one and the two-tone brown one are also Class 121s. The NSE one has lost its engines. The Chiltern blue and grey one is covered in the other topic.

The shoebeams on the green and maroon ones are for carrying the tripcocks so that they can work over London Underground lines.

Why?

 

[PhilJ W]

They have now been withdrawn because of lack of spares. The NSE liveried example had probably 'donated' its engines to keep the others running. The green 117 is being retained in case of failure of the replacement train. >> http://districtdave....ad=14359&page=1

The replacement train can't be all that reliable then as the 3 car set was running about when I was over at Aylesbury earlier this month.

It is being used for driver training as well. There is a problem with the replacement train being too powerful and damaging lineside equipment, its operating pressure is no less than three times that of the old units.

[big jim]

the green one was in the depot the other week up and running while i was there and the blue grey one has been out road learning.

 

i quite fancy converting a lima 117 into the sandite unit

[lankyphil]

Why a whole 117 though?

 

I get the "if one engine goes then there's a spare to get you home," but why the whole adding an engine to a trailer car as well?

 

Surely just semi-perma-coupling two bubbles or ditching the trailer car from the 117 set would be cheaper/easier?

[Redkiterail]

the gradients are fierce near Chorlywood and add leaf fall you need alot of traction and power to get through

The 'trailer' car is in fact a driving car with the cab (and controls) removed. This also explains the presence of the former guards compartment. If you want to convert the Lima model it would be advisable to swap the cab from one of the driving units to the centre car and rearrange the vehicles, IIRC Lima also used the same chassis with the engine detail for the centre trailer.

P.S. The former cab was at the near end in photo #4.

[russellwar]

little off topic but what are they building behond the station. I went to school there and things look to be changing

[PhilJ W]

Having taken a closer look at the photographs it appears that the green unit consists of three DMBS's. A simple conversion from the Lima model.

[31A Driver]

I bet that Railcar shift fairly, being a power triple. We had a power twin in the last days of 101's at Cambridge, and its acceleration would almost match a class 317 emu.

 

I live about 100 metres from the Cambridge - Kings Lynn line, (which I also drive over) and DRS have the water jetting contact on EA Zone. Nothing better than being woken up at 1.30 in the morning by top and tail 37's being given serious thrash!

The replacement train for them is 'topped and tailed' by a pair of 66's. But the new train has already managed to put the LT signaling out of action north of Rickhamsworth during the rush hour.

Nope, 'tis different. I have one sitting on the shelf about to get a bit of tlc.

Its a moot point anyway as Chiltern used a converted DMBS for the centre car, if you want to model it it would be easier to do the same.

Apartment blocks.

These blocks have been like this for at least eighteen months and the council are starting to complain about them.

Thanks for the info PhilLJW - I'm puzzled that 977992 is said to be a DMBS? Assuming the left hand end in my pics was the 'cab' end (the patch of shiny roof suggests that its the cab end with the roof dome replaced with plain panels)that can't have been a guard's van where the big new door is because the van wasn't next to the cab. The other end of the vehicle can't be the cab end because the door/window layout is wrong. Surely this vehicle must have been a DMS? Interesting stuff - can anyone provide the original numbers of all three cars?

Thanks, mods, for moving this to the right place. It takes all my concentration to upload pictures - trying to get a topic in the right place would blow a fuse!

Having taken another good hard look at the photographs the one furthest away is a DMBS identified by the cutaway beneath the inward opening guards door. As neither of the other two have any evidence of such a door it is probable that they are both DMS.

The maroon 'bubble car' appears to be one of those converted for route training with additional windows and seats in the guards compartment.

Here are pictures of the centre car before and after conversion. http://www.railcar.c...9/117/51375.htm This shows before and after pics showing the rebuilt end just after conversion. I think they are mistaken in describing it as a DMBS as it appears to be a DMS.

[dmustu]

Looking at the pics, the middle car is certainly an ex DMS car. You can see the origional passenger door layout at the 'exhaust pipe' end, the other end with the roller shutter type door is the converted ex cab end.

Because its a Water jetter unit, and the only way to carry enough water to complete the diagram was to use 3 cars. In order to kep time all needed to be powered. Hence the converted DMS. Using bubbles was out as there were not enough of them around available, and you couldn't run the pipes through and walk through cabbed vehicles.
