RPSI B141

B141 was moved under its own power from the RPSI locomotive shed last weekend out into the winter sunshine.

Copied the photo below into this thread so as not to hijack the 121 sound chip discussion.

It's a super photo that shows the Murphy Models plate and thanks to DiveController for posting it.  I understand that in the real world the Murphy Models plate is at the No 1 cab end.  In the DCC world is that the forward cab, or the reverse cab, or does it matter?

TIA

I believe they were still referred to as No1 & No. 2 (no jokes please), not sure if forward etc make that much sense in a double cabbed loco, although I often have problems remembering which is which tbh

Easy enough in the real world.  No 1 cab has the Murphy Models plate and the short handrail.

B141 was repainted at Inchicore very recently (last month, I think?)

Thanks. She's looking rather resplendent!

Maybe a rerun of the 'Diesel Do'

It'll be a costly sum to have both locos mainline-certified... Over £70,000+

How does that cost break down, and for how long is certification valid?

5 years ago the OTMR equipment for Deltic 55019 alone was estimated at £18,000, and that has older TPWS already installed. So that'd be £36,000 for both locos without any ongoing certification work.

For operating in Northern Ireland there'd be AWS and TPWS installation and certifications, plus train radio. In the Republic, requires a train radio (if it hasn't been removed) and ETCS Level 1 will be coming and that's something to be determined but is a very expensive bit of kit.

I'd say £70,000 per loco is the bottom end estimate!

Which itself is 3 years old ("back in April we got permission for an Irish Rail crew to operate No.131 light engine to Dundalk from Whitehead", which was 2023). So costs have only gone one way since then
