Talk:MR-90

Configuration
The configuration of a MR-90 is motor/cab car + trailer + motor/cab car. The three are semipermanently coupled with two drawbars. The tightlock couplings are only at the ends of this combination (set). The train consists of three sets. I have used the service often enough to have observed this.

 * That is not what the cited source indicates. oknazevad (talk) 21:43, 17 August 2016 (UTC)
 * The source may just be wrong. I live close enough to have used the service often and looking at the rakes I have come to the conclusion that they are married triplets. I always counted 9 cars not ten, but I'll check again when I have a chance and take a photo. But regardless th motor car and the trailer are attached by a drawbar (haulage) and not by a version of the janney coupler. BTW where do you live?  Peter Horn User talk 14:40, 18 August 2016 (UTC)
 * The source is a spec sheet from the manufacturer; there's no doubt it is correct. Whereas you counting is not a reliable source, and is in fact original research. Especially when I've been in Montreal and examined photos, I see 8 or 10 car trains. Sorry, but the incorrect one is you. PS, I live in New Jersey, and actually have often found AMT interesting because of how much commonality of equipment there is with NJ Transit. But that's irrelevant; reliable sources are. oknazevad (talk) 14:46, 18 August 2016 (UTC)
 * Mea culpa, you and the Bombardier specs are right. earlier today I took the time st see two trains stop at the Bois Franc (AMT) station and indeed I counted five pantographs per train that implies a control car with motors and a trailer.  Peter Horn User talk 20:08, 18 August 2016 (UTC)
 * That's okay. We all make mistakes. It's exactly why we rely on sources for verification. oknazevad (talk) 20:27, 18 August 2016 (UTC)

A question
What is I phase or 1 phase electric current? Peter Horn User talk 22:53, 18 August 2016 (UTC)
 * Eureka, Single-phase electric power. Problem solved. Peter Horn User talk 23:03, 18 August 2016 (UTC)

Data
Some of the data/specs in MR-90 should be transferred to the infobox. Peter Horn User talk 14:55, 17 October 2016 (UTC)
