I left my mobile phone on the 21:41 service from Birmingham New Street to Wolverhampton on Friday 22nd Septermber. I tracked it and it appears to have travelled between Birmingham and Wolverhampton but it went dead fairly quickly. I have reported it on MissingX, but wondered if anyone knew what diagram the train was on, hence which depot it would end up in for overnight cleaning. The train was a London Northwestern liveried Class 350. Lesson learned - always fully charge your phone before starting any journey. (probably obvious to many).
I'm not to familiar with the LNWR operation, but from a quick look at RealTimeTrains, it appears the unit might have done this:
2W62 2107 Walsall to Wolverhampton 2207
2W65 2218 Wolverhampton to Birmingham New Street 2248
2W68 2312 Birmingham New Street to Wolverhampton 2339
2W71 2348 Wolverhampton to Birmingham New Street 0015
2C16 0041 Birmingham New Street to Coventry 0112*
5C16 0120 Coventry to Coventry Yard 0125*
*This is depending on if it coupled to 1Y81 2150 London Euston to Birmingham New Street at New Street, if so would've then worked to Coventry.
If this is the case, the unit is in Coventry Yard until tomorrow morning, but I must reiterate I'm unfamiliar with LNWR.
