Block All Salesforce IPs

I finally got so sick of receiving spam from Salesforce that I decided to make an IPTables rule list to block all of Salesforce’s address space from my mail server.

LNER Azuma IEP Class 800 800104 Test Run at Peterborough February 26th 2019

A walk along LNER’s new Azuma while stopped at Peterborough before making its departure north, possibly to Aberdeen via Grantham if the display was accurate. Only had an old mobile which died half way along and had to change to another phone, which is why there is a cut mid-walk. At the end we see the Azuma depart under diesel power (pantagraph down). Looking through the windows we can see the weights under seats, presumably to simulate passengers.

Weekend Engineering 9 – Short Layout Update

A short update on the layout, mainly about the bridge line along the back of the station. Sorry this video is so late, after filming the roof started to leak and we had to get the entire roof replaced on the layout building. This video was filmed before all that happened but not edited, and it got pushed back. This is also the reason I have not uploaded much recently. Next video I’ll talk about that a bit and hopefully have some progress on the layout.

Weekend Engineering 8 – Station Area & Retaining Walls

It has been a while since the last update, not much progress this time around as I have been too busy with work and repairing the building the layout is in. Sorry for the muffled sound, I used a new microphone for this episode but it appears it didn’t work right, I tried to correct most of it in software but still a bit off.
