Would've been interesting to see how it tracked on the signal berths.

As follows (as normal for an up direction diveunder train):

[05/07/22 19:38:05] CA 2K23 PBSTIN PB0864
[05/07/22 19:39:54] CA 2K23 PB0864 PB0490
[05/07/22 19:42:01] CA 2K23 PB0490 PB0488
[05/07/22 19:42:53] CA 2K23 PB0488 PB0476
[05/07/22 19:48:01] CA 2K23 PB0476 PB0470
[05/07/22 19:48:55] CA 2K23 PB0470 PB0444

The time at Werrington Junction was entered manually after the fact for some reason.

That’s going to take a while to fix I’m guessing.

is it buses for a while now?

Re-opened this morning, some pictures of the repairs in this twitter thread:

Question.

 

When these units are running on the power pack. (PP), is there rheostat (regenerative braking) still operational. 

 

Thank You in advanced for answer.

 

Terry.

Yes, in fact the rheostatic brake is primarily used in diesel mode. With the pantograph raised the trains primarily use regenerative braking instead, only falling back the the rheo brake through neutral sections. The 745s don't have a rheo brake at all, only regen, so have to fall back to pneumatic braking through neutral sections.

Were you 1 of the drivers on board?

No, I've been involved in some of the testing.

We had this discussion last night. The cambridge service stops at Parkeston (Harwich International) and then returns to cambridge from there. As far as we know there are no plans to continue it to Harwich

town, so why there? But it's just dawned on me that AGA are building their new depot on land, on the down side, between Dovercourt and Parkeston which will have a wheel laith and other maintenance services. Maybe it's in readiness for that?

5Q58/67 only went to Dovercourt because of timing constraints on the single line, on the later 5Q68/69 we went all the way to Harwich Town.

Dovercourt & Harwich Town platforms are only being tested for future proofing at the moment though, nothing to do with the new Parkeston depot.
